Templates";s:11:"description";s:1198:"HTML_Template_IT: Simple template API. The Isotemplate API is somewhat tricky for a beginner although it is the best one you can build. template::parse() [phplib template = Isotemplate] requests you to name a source and a target where the current block gets parsed into. Source and target can be block names or even handler names. This API gives you a maximum of fexibility but you always have to know what you do which is quite unusual for php skripter like me. I noticed that I do not any control on which block gets parsed into which one. If all blocks are within one file, the script knows how they are nested and in which way you have to parse them. IT knows that inner1 is a child of block2, there's no need to tell him about this. Features : * Nested blocks * Include external file * Custom tags format (default {mytag}) HTML_Template_ITX : With this class you get the full power of the phplib template class. You may have one file with blocks in it but you have as well one main file and multiple files one for each block. This is quite usefull when you have user configurable websites.

It provides a common API for all supported RDBMS. The main difference to most other DB abstraction packages is that MDB2 goes much further to ensure portability. MDB2 provides most of its many features optionally that can be used to construct portable SQL statements: * Object-Oriented API * A DSN (data source name) or array format for specifying database servers * Datatype abstraction and on demand datatype conversion * Various optional fetch modes to fix portability issues * Portable error codes * Sequential and non sequential row fetching as well as bulk fetching * Ability to make buffered and unbuffered queries * Ordered array and associative array for the fetched rows * Prepare/execute (bind) named and unnamed placeholder emulation * Sequence/autoincrement emulation * Replace emulation * Limited sub select emulation * Row limit emulation * Transactions/savepoint support * Large Object support * Index/Unique Key/Primary Key support * Pattern matching abstraction * Module framework to load advanced functionality on demand * Ability to read the information schema * RDBMS management methods (creating, dropping, altering) * Reverse engineering schemas from an existing database * SQL function call abstraction * Full integration into the PEAR Framework * PHPDoc API documentation";s:4:"lead";a:4:{s:4:"name";s:17:"Lukas Kahwe

support for numeric types (Request #7170) - added statement_format option to make it possible to define the name used for native statements if supported - fixed bug when setting MDB2_PREPARE_RESULT in autoExecute() - fixed notice in exec() call in autoExecute() - reversed if logic in MDB2::fileExists checking to be more fool proof with safe_mode restrictions (Bug #8296) - moved CREATE TABLE query generation in a separate method for reuse in the drivers - added testLOBRead to test multiple LOB reads - fixed getColumnNames() optional parameter handling (Bug #8857) - phpdoc fix for fetchCol/fetchAll - added an extra if in the autoExecute method of the Extended driver (Bug #8878) - expanded tableInfo() tests - expanded prepare() tests - fix the incorrect use of currID() for lastInsertID() emulation (Bug #9107) - add test for lastInsertID() - also output php version in test results - added supported 'new_link' - dropped use of track_errors because 5.2.0 causes php_errormsg to not get populated if a custom error handler is set and it was causing issues for safe_mode users anyways - added some error handling into the bindValues()/bindParams() methods (Bug #9133) - bindValue() does not need values by reference - fix issue in execute() when parameter is a scalar integer of 0 (Bug #9158) - implemented stream_stat() method (Bug #9092) - better deal with non scalar arguments in test helper function as 5.2.0 explodes otherwise - extracted _skipDelimitedStrings() method from prepare() - added test for _skipDelimitedStrings() method - migrated to package.xml version 2 open todo items: - handle autoincrement fields in alterTable() - add length handling to LOB reverse engineering - expand charset support in schema management and result set handling (Request #4666) - add EXPLAIN abstraction - add cursor support along the lines of PDO (Request #3660 etc.) - add PDO based drivers, especially a driver to support SQLite 3 (Request #6907) - add support to export/import in CSV format - add more functions to the Function module (MD5(), IFNULL(), LENGTH() etc.) - add support for database/table/row LOCKs - add support for FOREIGN KEYs and CHECK (ENUM as possible mysql fallback) constraints - generate STATUS file from test suite results and allow users to submit test results - explore use of install groups (pear install MDB2#mysql) - add support for full text index creation and querying - add tests to check if the RDBMS specific handling with portability options disabled behaves as expected - handle implicit commits (like for DDL) in any affected driver (mysql, sqlite..) - add a getTableFieldsDefinitions() method to be used in tableInfo() - drop ILIKE from matchPattern() and instead add a second parameter to handle case

support for numeric types (Request #7170) - added statement_format option to make it possible to define the name used for native statements if supported - fixed bug when setting MDB2_PREPARE_RESULT in autoExecute() - fixed notice in exec() call in autoExecute() - reversed if logic in MDB2::fileExists checking to be more fool proof with safe_mode restrictions (Bug #8296) - moved CREATE TABLE query generation in a separate method for reuse in the drivers - added testLOBRead to test multiple LOB reads - fixed getColumnNames() optional parameter handling (Bug #8857) - phpdoc fix for fetchCol/fetchAll - added an extra if in the autoExecute method of the Extended driver (Bug #8878) - expanded tableInfo() tests - expanded prepare() tests - fix the incorrect use of currID() for lastInsertID() emulation (Bug #9107) - add test for lastInsertID() - also output php version in test results - added supported 'new_link' - dropped use of track_errors because 5.2.0 causes php_errormsg to not get populated if a custom error handler is set and it was causing issues for safe_mode users anyways - added some error handling into the bindValues()/bindParams() methods (Bug #9133) - bindValue() does not need values by reference - fix issue in execute() when parameter is a scalar integer of 0 (Bug #9158) - implemented stream_stat() method (Bug #9092) - better deal with non scalar arguments in test helper function as 5.2.0 explodes otherwise - extracted _skipDelimitedStrings() method from prepare() - added test for _skipDelimitedStrings() method - migrated to

MDB2 2.x breaks backwards compatibility in many ways in order to simplify the API for both users and drivers developers. Please note that currently only the MySQL, the PostGreSQL and the Oracle driver have been tested to pass the test suite. Here follows a short list of the most important changes: - all code that is not necessary for basic operation is now separateed into separate modules which can be loaded with the loadModule() method - all datatype related methods have been moved to a dataype module with the notable exception of getValue() and the newly introduced getDeclaration() - added extended module for highlevel methods - all manager method are no longer available in the core class and or now only available in the manager module - all reverse engineering methods have been taken from the manager class and are now available through the reverse module - a new module has been added to allow the addition of methods with RDBMS specific functionality (like getting the last autoincrement ID) - LOB handling has been greatly simplified - several methods names have been shortend - the fetch.+() methods do not free the result set anymore - the Manager and the reverse_engineer_xml_schema have been moved into a Tools directory - all parameters are now lowercased with underscores as separators - all drivers now support all of the dsn options that PEAR DB supports - several methods have been removed because they

License";s:13:"release_notes";s:3085:"- added charset and collation support to field declaration - added SQL comments and quoted identifier handling inside prepared statement parser - expanded length/scale support for numeric types (Request #7170) - added statement_format option to make it possible to define the name used for native statements if supported - fixed bug when setting MDB2_PREPARE_RESULT in autoExecute() - fixed notice in exec() call in autoExecute() - reversed if logic in MDB2::fileExists checking to be more fool proof with safe_mode restrictions (Bug #8296) - moved CREATE TABLE query generation in a separate method for reuse in the drivers - added testLOBRead to test multiple LOB reads - fixed getColumnNames() optional parameter handling (Bug #8857) - phpdoc fix for fetchCol/fetchAll - added an extra if in the autoExecute method of the Extended driver (Bug #8878) - expanded tableInfo() tests - expanded prepare() tests - fix the incorrect use of currID() for lastInsertID() emulation (Bug #9107) - add test for lastInsertID() - also output php version in test results - added supported 'new_link' - dropped use of track_errors because 5.2.0 causes php_errormsg to not get populated if a custom error handler is set and it was causing issues for safe_mode users anyways - added some error handling into the bindValues()/bindParams() methods (Bug #9133) - bindValue() does not need values by reference - fix issue in execute() when parameter is a scalar integer of 0 (Bug #9158) - implemented stream_stat() method (Bug #9092) - better deal with non scalar arguments in test helper function as 5.2.0 explodes otherwise - extracted _skipDelimitedStrings() method from prepare() - added test for _skipDelimitedStrings() method - migrated to package.xml version 2 open todo items: - handle autoincrement fields in alterTable() - add length handling to LOB reverse engineering - expand charset support in schema management and result set handling (Request #4666) - add EXPLAIN abstraction - add cursor support along the lines of PDO (Request #3660 etc.) - add PDO based drivers, especially a driver to support SQLite 3 (Request #6907) - add support to export/import in CSV format - add more functions to the Function module (MD5(), IFNULL(), LENGTH() etc.) - add support for database/table/row LOCKs - add support for FOREIGN KEYs and CHECK (ENUM as possible mysql fallback) constraints - generate STATUS file from test suite results and allow users to submit test results - explore use of install groups (pear install MDB2#mysql) - add support for full text index creation and querying - add tests to check if the RDBMS specific handling with portability options disabled behaves as expected - handle implicit commits (like for DDL) in any affected driver (mysql, sqlite..) - add a getTableFieldsDefinitions() method to be used in tableInfo() - drop ILIKE from matchPattern() and instead add a second parameter to handle case sensitivity with arbitrary operators - add charset and collation support to field declaration in all drivers - handle LOBs in buffered result sets (Request

[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary.

"; echo " .mtime :'".$v_list[$i][mtime]."' (".date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")
"; echo " .mode :'".$v_list[$i][mode]."'
"; echo " .uid :'".$v_list[$i][uid]."'
"; echo " .gid :'".$v_list[$i][gid]."'
"; echo " .typeflag :'".$v_list[$i][typeflag]."'
"; } // ----- Extracting the archive in directory "install" $tar_object->extract("install"); Public arguments : ------------------ None Public Methods : ---------------- Method : Archive_Tar($p_tarname, $compress = null) Description : Archive_Tar Class constructor. This flavour of the constructor only declare a new Archive_Tar object, identifying it by the name of the tar file. If the compress argument is set the tar will be read or created as a gzip or bz2 compressed TAR file. Arguments : $p_tarname : A valid filename for the tar archive file. $p_compress : can be null, 'gz' or 'bz2'. For compatibility reason it can also be true. This parameter indicates if gzip or bz2 compression is required. Return value : The Archive_Tar object. Sample : $tar_object = new Archive_Tar("tarname.tar"); $tar_object_compressed = new Archive_Tar("tarname.tgz", true); How it works : Initialize the object. Method : create($p_filelist) Description : This method creates the archive file and add the files / directories that are listed in $p_filelist. If the file already exists and is writable, it is replaced by the new tar. It is a create and not an add. If the file exists and is read-only or is a directory it is not replaced. The method return false and a PEAR error text. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. See also createModify() method for more details. Arguments : $p_filelist : An array of filenames and directory names, or a single string with names separated by a single blank space. Return value : true on success, false on error. Sample 1 : $tar_object = new Archive_Tar("tarname.tar"); $tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling $v_list[0]="file.txt"; $v_list[1]="data/"; (Optional '/' at the end) $v_list[2]="file.log"; $tar_object->create($v_list); Sample 2 : $tar_object = new Archive_Tar("tarname.tar"); $tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling $tar_object->create("file.txt data/ file.log"); How it works : Just calling the createModify() method with the right parameters. Method : createModify($p_filelist, $p_add_dir, $p_remove_dir = "") Description : This method creates the archive file and add the files / directories that are listed in $p_filelist. If the file already exists and is writable, it is replaced by the new tar. It is a create and not an add. If the file exists and is read-only or is a directory it is not replaced. The method return false and a PEAR error text. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. The path indicated in $p_remove_dir will be removed from the memorized path of each file / directory listed when this path exists. By default nothing is removed (empty path "") The path indicated in $p_add_dir will be added at the beginning of the memorized path of each file / directory listed. However it can be set to empty "". The adding of a path is done after the removing of path. The path add/remove ability enables the user to prepare an archive for extraction in a different path than the origin files are. See also addModify() method for file adding properties. Arguments : $p_filelist : An array of filenames and directory names, or a single string with names separated by a single blank space. $p_add_dir : A string which contains a path to be added to the memorized path of each element in the list. $p_remove_dir : A string which contains a path to be removed from the memorized path of each element in the list, when relevant. Return value : true on success, false on error. Sample 1 : $tar_object = new Archive_Tar("tarname.tar"); $tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling $v_list[0]="file.txt"; $v_list[1]="data/"; (Optional '/' at the end) $v_list[2]="file.log"; $tar_object->createModify($v_list, "install"); // files are stored in the archive as : // install/file.txt // install/data // install/data/file1.txt // install/data/... all the files and sub-dirs of data/ // install/file.log Sample 2 : $tar_object = new Archive_Tar("tarname.tar"); $tar_object->setErrorHandling(PEAR_ERROR_PRINT); // Optional error handling $v_list[0]="dev/file.txt"; $v_list[1]="dev/data/"; (Optional '/' at the end) $v_list[2]="log/file.log"; $tar_object->createModify($v_list, "install", "dev"); // files are stored in the archive as : // install/file.txt // install/data // install/data/file1.txt // install/data/... all the files and sub-dirs of data/ // install/log/file.log How it works : Open the file in write mode (erasing the existing one if one), call the _addList() method for adding the files in an empty archive, add the tar footer (512 bytes block), close the tar file. Method : addModify($p_filelist, $p_add_dir, $p_remove_dir="") Description : This method add the files / directories listed in $p_filelist at the end of the existing archive. If the archive does not yet exists it is created. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. The path indicated in $p_remove_dir will be removed from the memorized path of each file / directory listed when this path exists. By default nothing is removed (empty path "") The path indicated in $p_add_dir will be added at the beginning of the memorized path of each file / directory listed. However it can be set to empty "". The adding of a path is done after the removing of path. The path add/remove ability enables the user to prepare an archive for extraction in a different path than the origin files are. If a file/dir is already in the archive it will only be added at the end of the archive. There is no update of the existing archived file/dir. However while extracting the archive, the last file will replace the first one. This results in a none optimization of the archive size. If a file/dir does not exist the file/dir is ignored. However an error text is send to PEAR error. If a file/dir is not readable the file/dir is ignored. However an error text is send to PEAR error. If the resulting filename/dirname (after the add/remove option or not) string is greater than 99 char, the file/dir is ignored. However an error text is send to PEAR error. Arguments : $p_filelist : An array of filenames and directory names, or a single string with names separated by a single blank space. $p_add_dir : A string which contains a path to be added to the memorized path of each element in the list. $p_remove_dir : A string which contains a path to be removed from the memorized path of each element in the list, when relevant. Return value : true on success, false on error. Sample 1 : $tar_object = new Archive_Tar("tarname.tar"); [...] $v_list[0]="dev/file.txt"; $v_list[1]="dev/data/"; (Optional '/' at the end) $v_list[2]="log/file.log"; $tar_object->addModify($v_list, "install"); // files are stored in the archive as : // install/file.txt // install/data // install/data/file1.txt // install/data/... all the files and sub-dirs of data/ // install/file.log Sample 2 : $tar_object = new Archive_Tar("tarname.tar"); [...] $v_list[0]="dev/file.txt"; $v_list[1]="dev/data/"; (Optional '/' at the end) $v_list[2]="log/file.log"; $tar_object->addModify($v_list, "install", "dev"); // files are stored in the archive as : // install/file.txt // install/data // install/data/file1.txt // install/data/... all the files and sub-dirs of data/ // install/log/file.log How it works : If the archive does not exists it create it and add the files. If the archive does exists and is not compressed, it open it, jump before the last empty 512 bytes block (tar footer) and add the files at this point. If the archive does exists and is compressed, a temporary copy file is created. This temporary file is then 'gzip' read block by block until the last empty block. The new files are then added in the compressed file. The adding of files is done by going through the file/dir list, adding files per files, in a recursive way through the directory. Each time a path need to be added/removed it is done before writing the file header in the archive. Method : add($p_filelist) Description : This method add the files / directories listed in $p_filelist at the end of the existing archive. If the archive does not yet exists it is created. The $p_filelist parameter can be an array of string, each string representing a filename or a directory name with their path if needed. It can also be a single string with names separated by a single blank. See addModify() method for details and limitations. Arguments : $p_filelist : An array of filenames and directory names, or a single string with names separated by a single blank space. Return value : true on success, false on error. Sample 1 : $tar_object = new Archive_Tar("tarname.tar"); [...] $v_list[0]="dev/file.txt"; $v_list[1]="dev/data/"; (Optional '/' at the end) $v_list[2]="log/file.log"; $tar_object->add($v_list); Sample 2 : $tar_object = new Archive_Tar("tarname.tgz", true); [...] $v_list[0]="dev/file.txt"; $v_list[1]="dev/data/"; (Optional '/' at the end) $v_list[2]="log/file.log"; $tar_object->add($v_list); How it works : Simply call the addModify() method with the right parameters. Method : addString($p_filename, $p_string) Description : This method add a single string as a file at the end of the existing archive. If the archive does not yet exists it is created. Arguments : $p_filename : A string which contains the full filename path that will be associated with the string. $p_string : The content of the file added in the archive. Return value : true on success, false on error. Sample 1 : $v_archive = & new Archive_Tar($p_filename); $v_archive->setErrorHandling(PEAR_ERROR_PRINT); $v_result = $v_archive->addString('data/test.txt', 'This is the text of the string'); Method : extract($p_path = "") Description : This method extract all the content of the archive in the directory indicated by $p_path.If $p_path is optional, if not set the archive is extracted in the current directory. While extracting a file, if the directory path does not exists it is created. See extractModify() for details and limitations. Arguments : $p_path : Optional path where the files/dir need to by extracted. Return value : true on success, false on error. Sample : $tar_object = new Archive_Tar("tarname.tar"); $tar_object->extract(); How it works : Simply call the extractModify() method with appropriate parameters. Method : extractModify($p_path, $p_remove_path) Description : This method extract all the content of the archive in the directory indicated by $p_path. When relevant the memorized path of the files/dir can be modified by removing the $p_remove_path path at the beginning of the file/dir path. While extracting a file, if the directory path does not exists it is created. While extracting a file, if the file already exists it is replaced without looking for last modification date. While extracting a file, if the file already exists and is write protected, the extraction is aborted. While extracting a file, if a directory with the same name already exists, the extraction is aborted. While extracting a directory, if a file with the same name already exists, the extraction is aborted. While extracting a file/directory if the destination directory exist and is write protected, or does not exist but can not be created, the extraction is aborted. If after extraction an extracted file does not show the correct stored file size, the extraction is aborted. When the extraction is aborted, a PEAR error text is set and false is returned. However the result can be a partial extraction that may need to be manually cleaned. Arguments : $p_path : The path of the directory where the files/dir need to by extracted. $p_remove_path : Part of the memorized path that can be removed if present at the beginning of the file/dir path. Return value : true on success, false on error. Sample : // Imagine tarname.tar with files : // dev/data/file.txt // dev/data/log.txt // readme.txt $tar_object = new Archive_Tar("tarname.tar"); $tar_object->extractModify("install", "dev"); // Files will be extracted there : // install/data/file.txt // install/data/log.txt // install/readme.txt How it works : Open the archive and call a more generic function that can extract only a part of the archive or all the archive. See extractList() method for more details. Method : extractInString($p_filename) Description : This method extract from the archive one file identified by $p_filename. The return value is a string with the file content, or NULL on error. Arguments : $p_filename : The path of the file to extract in a string. Return value : a string with the file content or NULL. Sample : // Imagine tarname.tar with files : // dev/data/file.txt // dev/data/log.txt // dev/readme.txt $v_archive = & new Archive_Tar('tarname.tar'); $v_archive->setErrorHandling(PEAR_ERROR_PRINT); $v_string = $v_archive->extractInString('dev/readme.txt'); echo $v_string; Method : listContent() Description : This method returns an array of arrays that describe each file/directory present in the archive. The array is not sorted, so it show the position of the file in the archive. The file informations are : $file[filename] : Name and path of the file/dir. $file[mode] : File permissions (result of fileperms()) $file[uid] : user id $file[gid] : group id $file[size] : filesize $file[mtime] : Last modification time (result of filemtime()) $file[typeflag] : "" for file, "5" for directory Arguments : Return value : An array of arrays or 0 on error. Sample : $tar_object = new Archive_Tar("tarname.tar"); if (($v_list = $tar_object->listContent()) != 0) for ($i=0; $i"; echo " .size :'".$v_list[$i][size]."'
"; echo " .mtime :'".$v_list[$i][mtime]."' (". date("l dS of F Y h:i:s A", $v_list[$i][mtime]).")
"; echo " .mode :'".$v_list[$i][mode]."'
"; echo " .uid :'".$v_list[$i][uid]."'
"; echo " .gid :'".$v_list[$i][gid]."'
"; echo " .typeflag :'".$v_list[$i][typeflag]."'
"; } How it works : Call the same function as an extract however with a flag to only go through the archive without extracting the files. Method : extractList($p_filelist, $p_path = "", $p_remove_path = "") Description : This method extract from the archive only the files indicated in the $p_filelist. These files are extracted in the current directory or in the directory indicated by the optional $p_path parameter. If indicated the $p_remove_path can be used in the same way as it is used in extractModify() method. Arguments : $p_filelist : An array of filenames and directory names, or a single string with names separated by a single blank space. $p_path : The path of the directory where the files/dir need to by extracted. $p_remove_path : Part of the memorized path that can be removed if present at the beginning of the file/dir path. Return value : true on success, false on error. Sample : // Imagine tarname.tar with files : // dev/data/file.txt // dev/data/log.txt // readme.txt $tar_object = new Archive_Tar("tarname.tar"); $tar_object->extractList("dev/data/file.txt readme.txt", "install", "dev"); // Files will be extracted there : // install/data/file.txt // install/readme.txt How it works : Go through the archive and extract only the files present in the list. catalog/libs/PEAR/docs/HTML_Template_IT/0000755577340101002240000000000010625427764021575 5ustar tonerlogicspg11675700000000000000catalog/libs/PEAR/docs/HTML_Template_IT/examples/0000755577340101002240000000000010625427761023410 5ustar tonerlogicspg11675700000000000000catalog/libs/PEAR/docs/HTML_Template_IT/examples/sample_it.php0000644577340101002240000000123010625427760026071 0ustar tonerlogicspg11675700000000000000 array('Stig', 'Bakken'), '1' => array('Martin', 'Jansen'), '2' => array('Alexander', 'Merz') ); $tpl = new HTML_Template_IT('./templates'); $tpl->loadTemplatefile('main.tpl.htm', true, true); foreach ($data as $name) { foreach ($name as $cell) { // Assign data to the inner block $tpl->setCurrentBlock('cell'); $tpl->setVariable('DATA', $cell); $tpl->parseCurrentBlock(); } // Assign data and the inner block to the // outer block $tpl->setCurrentBlock('row'); $tpl->parseCurrentBlock(); } // print the output $tpl->show(); ?> catalog/libs/PEAR/docs/HTML_Template_IT/examples/sample_itx_addblockfile.php0000644577340101002240000000405510625427761030755 0ustar tonerlogicspg11675700000000000000'mypackage', 'version' =>'1.0', 'changelog' => array ('fix bug #002', 'add author FOO to AUTHORS') ), array ('packagename'=>'mypackage', 'version' =>'1.0 RC 1', 'changelog' => array ('fix bug #002', 'added method foo()') ) ); $tpl = new HTML_Template_ITX('./templates'); $tpl->loadTemplatefile('addblockfile_main.tpl.htm', true, true); // The complete content of "addblockfile_main.tpl.htm" will be loaded into a block // called "list_template".

MDB2 data types

Introduction

All DBMS provide multiple choice of data types for the information that can be stored in their database table fields. However, the set of data types made available varies from DBMS to DBMS.

To simplify the interface with the DBMS supported by MDB2 it was defined a base set of data types that applications may access independently of the underlying DBMS.

The MDB2 applications programming interface takes care of mapping data types when managing database options. It is also able to convert that is sent to and received from the underlying DBMS using the respective driver.

  • Text data type

    • The text data type is available with two options for the length: one that is explicitly length limited and another of undefined length that should be as large as the database allows.

    The length limited option is the most recommended for efficiency reasons. The undefined length option allows very large fields but may prevent the use of indexes and may not allow sorting on fields of its type.

    The fields of this type should be able to handle 8 bit characters. Drivers take care of DBMS specific escaping of characters of special meaning with the values of the strings to be converted to this type.

  • Boolean data type

    • The boolean data type represents only two values that can be either 1 or 0. Do not assume that these data types are stored as integers because some DBMS drivers may implement this type with single character text fields for a matter of efficient. Ternary logic is possible by using null as the third possible value that may be assigned to fields of this type.

  • Integer data type

    • The integer data type may store integer values as large as each DBMS may handle. Fields of this type may be created optionally as unsigned integers but not all DBMS support it. Therefore, such option may be ignored. Truly portable applications should not rely on the availability of this option.

  • Decimal data type

    • The decimal data type may store decimal numbers accurately with a fixed number of decimal places. This data type is suitable for representing accurate values like currency amounts.

    Some DBMS drivers may emulate the decimal data type using integers. Such drivers need to know in advance how many decimal places that should be used to perform eventual scale conversion when storing and retrieving values from a database. Despite this, applications may use arithmetic expressions and functions with the values stored on decimal type fields as long as any constant values that are used in the expressions are also converted with the respective MDB2 conversion functions.

    The number of places that are used to the left and the right of the decimal point is pre-determined and fixed for all decimal values stored in the same database. By default, MDB2 uses 2 places to the right of the decimal point, but this may be changed when setting the database connection. The number of places available to the right of the decimal point depend on the DBMS.

    It is not recommended to change the number places used to represent decimal values in database after it is installed. MDB2 does not keep track of changes in the number of decimal places.

  • Float data type

    • The float data type may store floating point decimal numbers. This data type is suitable for representing numbers within a large scale range that do not require high accuracy. The scale and the precision limits of the values that may be stored in a database depends on the DBMS that it is used.

  • Date data type

    • The date data type may represent dates with year, month and day. DBMS independent representation of dates is accomplished by using text strings formatted according to the IS0 8601 standard.

    The format defined by the ISO 8601 standard for dates is YYYY-MM-DD where YYYY is the number of the year (Gregorian calendar), MM is the number of the month from 1 to 12 and DD is the number of the day from 1 to 31. Months or days numbered below 10 should be padded on the left with 0.

    Some DBMS have native support for date formats, but for others the DBMS driver may have to represent them as integers or text values. In any case, it is always possible to make comparisons between date values as well sort query results by fields of this type.

  • Time data type

    • The time data type may represent the time of a given moment of the day. DBMS independent representation of the time of the day is also accomplished by using text strings formatted according to the IS0 8601 standard.

    The format defined by the ISO 8601 standard for the time of the day is HH:MI:SS where HH is the number of hour the day from 0 to 23 and MI and SS are respectively the number of the minute and of the second from 0 to 59. Hours, minutes and seconds numbered below 10 should be padded on the left with 0.

    Some DBMS have native support for time of the day formats, but for others the DBMS driver may have to represent them as integers or text values. In any case, it is always possible to make comparisons between time values as well sort query results by fields of this type.

  • Time stamp data type

    • The time stamp data type is a mere combination of the date and the time of the day data types. The representation of values of the time stamp type is accomplished by joining the date and time string values in a single string joined by a space. Therefore, the format template is YYYY-MM-DD HH:MI:SS. The represented values obey the same rules and ranges described for the date and time data types.

  • Large object (file) data types

    • The large object data types are meant to store data of undefined length that may be to large to store in text fields, like data that is usually stored in files.

    MDB2 supports two types of large object fields: Character Large OBjects (CLOBs) and Binary Large OBjects (BLOBs). CLOB fields are meant to store only data made of printable ASCII characters. BLOB fields are meant to store all types of data.

    Large object fields are usually not meant to be used as parameters of query search clause (WHERE) unless the underlying DBMS supports a feature usually known as "full text search".

PEAR MDB2 is a project to merge PEAR DB and Metabase into one DB
abstraction layer.

You can get info on these at:
  PEAR DB: http://pear.php.net
  Metabase: http://phpclasses.upperdesign.com/browse.html/package/20/

At these URLs you will also find the licensing information on these two
projects along with the credits.

Actually MDB2 is the second major version of MDB.
The main differences between the new MDB2 and the old MDB version is
that the API has been drastically refactored to clean up the API
and improve performance.

If you have any questions or suggestions you can contact me (Lukas Smith)
at this email address:
  smith@backendmedia.com
Co-Author is Christopher Linn:
  clinn@backendmedia.com

Or even better post a message to pear-dev@lists.php.net mailinglist for
development related questions of the MDB2 package itself. For questions
using MDB2 pelase direct your questions at pear-general@lists.php.net.

** Features

MDB2 provides a common API for all support RDBMS. The main difference to most
other DB abstraction packages is that MDB2 goes much further to ensure
portability. Among other things MDB2 features:
* An OO-style query API
* A DSN (data source name) or array format for specifying database servers
* Datatype abstraction and on demand datatype conversion
* Portable error codes
* Sequential and non sequential row fetching as well as bulk fetching
* Ordered array and associative array for the fetched rows
* Buffered and Unbuffered fetching
* Prepare/execute (bind) emulation
* Sequence emulation
* Replace emulation
* Limited Subselect emulation
* Row limit support
* Transactions support
* Large Object support
* Index/Unique support
* Extension Framework to load advanced functionality on demand
* Table information interface
* RDBMS management methods (creating, dropping, altering)
* RDBMS independent xml based schema definition management
* Altering of a DB from a changed xml schema
* Reverse engineering of xml schemas from an existing DB (currently MySQL and PgSQl)
* Full integration into the PEAR Framework
* PHPDoc API documentation

** Getting started:

I would first recommend taking a look at example.php.
This should give you a general feel of how to interact with MDB2.

After that you may want to take a look at the rather large API
at www.backendmedia.com/MDB2/docs. There you will also find a document
describing the xml schema format and a little tutorial (it was
just recently ported from Metabase, so it may contain errors).

** Current State:

The current release can be found at the PEAR webpage:
  http://pear.php.net/package-info.php?package=MDB2

** Package Content:

As a user the only php script you will need to include is MDB2.php which will
install to your PEAR root directory. All other files and their containing
classes will be included via MDB2::factory(), MDB2::connect(), MDB2::singleton().

These will load additional classes. Most classes are loaded on demand.

Furthermore MDB2 provides an extensive testing framework that works through a
browser and command line interface. There are several other test that test the
two wrappers. These files will install into your test dir found in the
PEAR root dir.

** Documentation:

You can find the still incomplete documentation for MDB2 here:
http://pear.php.net/manual/en/package.database.mdb2.php

PHPDoc generated documentation can be found at:
http://www.backendmedia.com/MDB2/docs/

The entire "public" API and most of the "private" methods (except for some of
the lob classes) have been documented with PHPDoc comments. Most of the API
is borrowed from extPDO, so you can look there for detailed documentation.
Since there are a large number of new methods available thanks to the Metabase
heritage of MDB2 you will also have to take a look in the Metabase documentation
(which can be found at the URL mentioned above, but does require that
you register with phpclasses). Most of these Metabase functions have
been renamed and changed considerably. The main things left are the datatypes
and the manager module.

For example ($db being an MDB2 object):
  $converted_value = MetabaseGetTimestampFieldValue($database, $value);
would now be
  $converted_value = $db->quote($value, 'timestamp');

If you want to help out with documentation please email me.

** Testing:

For most of the tests you can set the username/password/hostname in the relevant
config file. The user will need to have the right to create new databases.

test.php/clitest.php/testchoose.php: Is the native testing suite provided by
MDB2. Please see the README in the tests directory for details.

example.php: Several test calls to MDB2's native API. It require PEAR::VAR_Dump
package and are configured to use the following settings:
username = metapear
password = funky
hostname = localhost

** How to write new Drivers:

Skeleton drivers are provided in the docs directory of the MDB2 package.

The best course of action would be to take a MDB2 driver and hack it to fit
the new RDBMS. This will surely be faster and it will ensure that the new
driver takes full advantage of the MDB2 framework. I would however recommend
working with the existing Metabase driver for inspiration that RDBMS when
doing those changes.

In order to check compliance of the driver with MDB2 you can use the testing
suite (see the "testing" section above)

** History

MDB was started after Manuel broad be into the discussion about getting the
features of Metabase into PEAR that was going on (again) in December 2001. He
suggested that I could take on this project. After alot of discussion about
how when and if etc I started development in February 2002.

MDB is based on Metabase but has been reworked severely to better match
the PEAR DB API and PEAR CS. The approach I have taken so far is to take DB.php
from PEAR DB and make it create a Metabase object. I have changed the
Metabase structure slightly. The formatting has been reworked
considerably to better fit the final structure (MDB standalone with a
BC-wrapper for Metabase and PEAR DB), to fit the PEAR CS and to make it
easier for other people to contribute.

The metabase_interface.php was been renamed to metabase_wrapper.php and
now only serves as a wrapper to keep BC with Metabase. A wrapper will
have to be created for PEAR DB as well.

Basically the result is a Metabase that is really close to the PEAR DB
structure. I have also added any missing methods from PEAR DB. Work on
moving the error handling to PEAR error handling is under way but still
needs some work.

In MDB2 the API was heavily refactored to be even more streamlined. Redundant
features have been removed. Some features where moved out of the core into
separate loadable modules. Instead of resources resultsets are now wrapped
into objects similar to PEAR DB.

** Credits (never to early for those huh? :-)  ):

I would especially like to thank Manuel Lemos (Author of Metabase) for
getting me involved in this and generally being around to ask questions.
I would also like to thank Tomas Cox and Stig S. Bakken from the PEAR
projects for help in undertstanding PEAR, solving problems and trusting
me enough. Paul Cooper for the work on the pgsql driver. Furthermore I
would like to thank Alex Black for being so enthusiastic about this
project and offering binarycloud as a test bed for this project.
Christian Dickmann for being the first to put MDB to some real use,
making MDB use PEAR Error and working on the XML schema manager.

Finally Peter Bowyer for starting the discussion that made people pick
up this project again after the first versions of what was then called
"metapear" have been ideling without much feedback. I guess I should
also thank BackendMedia (my company :-)  ) for providing the necessary means
to develop this on company time (actually for the most part my entire
life is company time ... so it goes)catalog/libs/PEAR/docs/MDB2/docs/STATUS0000644577340101002240000000236010625427775021167 0ustar  tonerlogicspg11675700000000000000STATUS OF THE PEAR MDB2 PACKAGE

=========================
Installing the PEAR Installer.

You should install PEAR on a local development machine first.  Installing
PEAR on a remote production machine should only be done after you are
familiar with PEAR and have tested code using PEAR on your development
machine.

There are two methods of installing PEAR
 - PEAR bundled in PHP
 - go-pear

We will first examine how to install PEAR that is bundled with PHP.

Microsoft Windows
=================
If you are running PHP 5.2.0 or newer, simply download and
run the windows installer (.msi) and PEAR can be automatically
installed.

Otherwise, for older PHP versions, download the .zip of windows,
there is a script included with your PHP distribution that is called
"go-pear".  You must open a command box in order to run it.  Click
"start" then click "Run..." and type "cmd.exe" to open a command box.
Use "cd" to change directory to the location of PHP where you unzipped it,
and run the go-pear command.

Unix
====
make sure you have enabled default extensions, and if you want faster
downloads, enable the zlib extension.  You must also enable the CLI
SAPI with the --enable-cli extension directive.  After this, simply run:

make install-pear

and PEAR will be automatically configured for you.

go-pear
=======
For users who cannot perform the above steps, or who wish to obtain the
latest PEAR with a slightly higher risk of failure, use go-pear.  go-pear
is obtained by downloading http://go-pear.org and saving it as go-pear.php.
After downloading, simply run "php go-pear.php" or open it in a web browser
(windows only) to download and install PEAR.

You can always ask general installation questions on pear-general@lists.php.net,
a public mailing list devoted to support for PEAR packages and installation-
related issues.

Happy PHPing, we hope PEAR will be a great tool for your development work!

=========================

What is the PEAR Installer?  What is PEAR?

PEAR is the PHP Extension and Application Repository, found at
http://pear.php.net.  The PEAR Installer is this software, which
contains executable files and PHP code that is used to download
and install PEAR code from pear.php.net.

PEAR contains useful software libraries and applications such as
MDB2 (database abstraction), HTML_QuickForm (HTML forms management),
PhpDocumentor (auto-documentation generator), DB_DataObject
(Data Access Abstraction), and many hundreds more.  Browse all
available packages at http://pear.php.net, the list is constantly
growing and updating to reflect improvements in the PHP language.

DOCUMENTATION
=============

Documentation for PEAR can be found at http://pear.php.net/manual/.
Installation documentation can be found in the INSTALL file included
in this tarball.

WARNING: DO NOT RUN PEAR WITHOUT INSTALLING IT - if you downloaded this
tarball manually, you MUST install it.  Read the instructions in INSTALL
prior to use.


Happy PHPing, we hope PEAR will be a great tool for your development work!

    The Structures_Graph class represents a graph data structure.
    

    A Graph is a data structure composed by a set of nodes, connected by arcs.  Graphs may either be directed or undirected. In a directed graph, arcs are  directional, and can be traveled only one way. In an undirected graph, arcs  are bidirectional, and can be traveled both ways.

    The Structures_Graph_Manipulator_AcyclicTest is a graph manipulator  which tests whether a graph contains a cycle.
    

    The definition of an acyclic graph used in this manipulator is that of a  DAG. The graph must be directed, or else it is considered cyclic, even when  there are no arcs.

    The Structures_Graph_Node class represents a Node that can be member of a  graph node set.
    

    A graph node can contain data. Under this API, the node contains default data,  and key index data. It behaves, thus, both as a regular data node, and as a  dictionary (or associative array) node.
    Regular data is accessed via getData and setData. Key indexed data is accessed  via getMetadata and setMetadata.

    Node metadata getter
    

    Each graph node can contain multiple 'metadata' entries, each stored under a different key, as in an  associative array or in a dictionary. This method gets the data under the given key. If the key does  not exist, an error will be thrown, so testing using metadataKeyExists might be needed.

    Calculate the in degree of the node.
    

    The indegree for a node is the number of arcs entering the node. For non directed graphs,  the indegree is equal to the outdegree.

    Test for existence of metadata under a given key.
    

    Each graph node can contain multiple 'metadata' entries, each stored under a different key, as in an  associative array or in a dictionary. This method tests whether a given metadata key exists for this node.

    Calculate the out degree of the node.
    

    The outdegree for a node is the number of arcs exiting the node. For non directed graphs,  the outdegree is always equal to the indegree.

    Delete metadata by key
    

    Each graph node can contain multiple 'metadata' entries, each stored under a different key, as in an  associative array or in a dictionary. This method removes any data that might be stored under the provided key.  If the key does not exist, no error is thrown, so it is safe using this method without testing for key existence.

    Structures_Graph Tutorial
    
  
    A first tour of graph datastructure manipulation
    
 
    Introduction
    Structures_Graph is a package for creating and manipulating graph datastructures. A graph is a set of objects, called nodes, connected by arcs. When used as a datastructure, usually nodes contain data, and arcs represent relationships between nodes. When arcs have a direction, and can be travelled only one way, graphs are said to be directed. When arcs have no direction, and can always be travelled both ways, graphs are said to be non directed.
    
  
    Structures_Graph provides an object oriented API to create and directly query a graph, as well as a set of Manipulator classes to extract information from the graph.
    
 
    Creating a Graph
    Creating a graph is done using the simple constructor:
   
    require_once 'Structures/Graph.php';

$directedGraph =& new Structures_Graph(true);
$nonDirectedGraph =& new Structures_Graph(false);
    
    
   and passing the constructor a flag telling it whether the graph should be directed. A directed graph will always be directed during its lifetime. It's a permanent characteristic.
    
  
    To fill out the graph, we'll need to create some nodes, and then call Graph::addNode.
   
    require_once 'Structures/Graph/Node.php';

$nodeOne =& new Structures_Graph_Node();
$nodeTwo =& new Structures_Graph_Node();
$nodeThree =& new Structures_Graph_Node();

$directedGraph->addNode(&$nodeOne);
$directedGraph->addNode(&$nodeTwo);
$directedGraph->addNode(&$nodeThree);
    
    
   and then setup the arcs:
   
    $nodeOne->connectTo($nodeTwo);
$nodeOne->connectTo($nodeThree);
    
    
   Note that arcs can only be created after the nodes have been inserted into the graph.
    
 
    Associating Data
    Graphs are only useful as datastructures if they can hold data. Structure_Graph stores data in nodes. Each node contains a setter and a getter for its data.
   
    $nodeOne->setData("Node One's Data is a String");
$nodeTwo->setData(1976);
$nodeThree->setData('Some other string');

print("NodeTwo's Data is an integer: " . $nodeTwo->getData());
    
    
  
    Structure_Graph nodes can also store metadata, alongside with the main data. Metadata differs from regular data just because it is stored under a key, making it possible to store more than one data reference per node. The metadata getter and setter need the key to perform the operation:
   
    $nodeOne->setMetadata('example key', "Node One's Sample Metadata");
print("Metadata stored under key 'example key' in node one: " . $nodeOne->getMetadata('example key'));
$nodeOne->unsetMetadata('example key');
    
    
 
    Querying a Graph
    Structures_Graph provides for basic querying of the graph:
   
    // Nodes are able to calculate their indegree and outdegree
print("NodeOne's inDegree: " . $nodeOne->inDegree());
print("NodeOne's outDegree: " . $nodeOne->outDegree());

// and naturally, nodes can report on their arcs
$arcs = $nodeOne->getNeighbours();
for ($i=0;$i<sizeof($arcs);$i++) {
    print("NodeOne has an arc to " . $arcs[$i]->getData());
}

  Structures_Graph Tutorial
  A first tour of graph datastructure manipulation
 
 
  Introduction
  
  Structures_Graph is a package for creating and manipulating graph datastructures. A graph is a set of objects, called nodes, connected by arcs. When used as a datastructure, usually nodes contain data, and arcs represent relationships between nodes. When arcs have a direction, and can be travelled only one way, graphs are said to be directed. When arcs have no direction, and can always be travelled both ways, graphs are said to be non directed.
  
  
  Structures_Graph provides an object oriented API to create and directly query a graph, as well as a set of Manipulator classes to extract information from the graph.
  
 
 
  Creating a Graph
  
   Creating a graph is done using the simple constructor:
   
    
   
   and passing the constructor a flag telling it whether the graph should be directed. A directed graph will always be directed during its lifetime. It's a permanent characteristic.
  
  
  To fill out the graph, we'll need to create some nodes, and then call Graph::addNode.
   
    addNode(&$nodeOne);
$directedGraph->addNode(&$nodeTwo);
$directedGraph->addNode(&$nodeThree);
    ]]>
   
   and then setup the arcs:
   
    connectTo($nodeTwo);
$nodeOne->connectTo($nodeThree);
    ]]>
   
   Note that arcs can only be created after the nodes have been inserted into the graph. 
  
 
 
  Associating Data
  
  Graphs are only useful as datastructures if they can hold data. Structure_Graph stores data in nodes. Each node contains a setter and a getter for its data.
   
    setData("Node One's Data is a String");
$nodeTwo->setData(1976);
$nodeThree->setData('Some other string');

print("NodeTwo's Data is an integer: " . $nodeTwo->getData());
    ]]>
   
  
  
  Structure_Graph nodes can also store metadata, alongside with the main data. Metadata differs from regular data just because it is stored under a key, making it possible to store more than one data reference per node. The metadata getter and setter need the key to perform the operation:
   
    setMetadata('example key', "Node One's Sample Metadata");
print("Metadata stored under key 'example key' in node one: " . $nodeOne->getMetadata('example key'));
$nodeOne->unsetMetadata('example key');
    ]]>
   
  
 
 
  Querying a Graph
  
  Structures_Graph provides for basic querying of the graph:
   
    inDegree());
print("NodeOne's outDegree: " . $nodeOne->outDegree());

// and naturally, nodes can report on their arcs
$arcs = $nodeOne->getNeighbours();
for ($i=0;$igetData());
}
    ]]>

/**
 * Integrated Template - IT
 *
 * Well there's not much to say about it. I needed a template class that
 * supports a single template file with multiple (nested) blocks inside and
 * a simple block API.
 *
 * The Isotemplate API is somewhat tricky for a beginner although it is the best
 * one you can build. template::parse() [phplib template = Isotemplate] requests
 * you to name a source and a target where the current block gets parsed into.
 * Source and target can be block names or even handler names. This API gives you
 * a maximum of fexibility but you always have to know what you do which is
 * quite unusual for php skripter like me.
 *
 * I noticed that I do not any control on which block gets parsed into which one.
 * If all blocks are within one file, the script knows how they are nested and in
 * which way you have to parse them. IT knows that inner1 is a child of block2, there's
 * no need to tell him about this.
 *
 * 
 *   
 *     
 *   
 *   
 *     
 *     
 *   
 * 
    
 *       __global__
 *       
    
 *       (hidden and automatically added)
 *     
    block1
 *       
 *         
 *           
 *         
 *         
 *           
 *           
 *         
 *       
    block2
    inner1inner2
    
 *     
    
 *
 * To add content to block1 you simply type:
 * $tpl->setCurrentBlock("block1");
 * and repeat this as often as needed:
 * 
 *   $tpl->setVariable(...);
 *   $tpl->parseCurrentBlock();
 * 
 *
 * To add content to block2 you would type something like:
 * 
 * $tpl->setCurrentBlock("inner1");
 * $tpl->setVariable(...);
 * $tpl->parseCurrentBlock();
 *
 * $tpl->setVariable(...);
 * $tpl->parseCurrentBlock();
 *
 * $tpl->parse("block1");
 * 
 *
 * This will result in one repition of block1 which contains two repitions
 * of inner1. inner2 will be removed if $removeEmptyBlock is set to true which is the default.
 *
 * Usage:
 * 
 * $tpl = new HTML_Template_IT( [string filerootdir] );
 *
 * // load a template or set it with setTemplate()
 * $tpl->loadTemplatefile( string filename [, boolean removeUnknownVariables, boolean removeEmptyBlocks] )
 *
 * // set "global" Variables meaning variables not beeing within a (inner) block
 * $tpl->setVariable( string variablename, mixed value );
 *
 * // like with the Isotemplates there's a second way to use setVariable()
 * $tpl->setVariable( array ( string varname => mixed value ) );
 *
 * // Let's use any block, even a deeply nested one
 * $tpl->setCurrentBlock( string blockname );
 *
 * // repeat this as often as you need it.
 * $tpl->setVariable( array ( string varname => mixed value ) );
 * $tpl->parseCurrentBlock();
 *
 * // get the parsed template or print it: $tpl->show()
 * $tpl->get();

/**
* Integrated Template Extension - ITX
*
* With this class you get the full power of the phplib template class.
* You may have one file with blocks in it but you have as well one main file
* and multiple files one for each block. This is quite usefull when you have
* user configurable websites. Using blocks not in the main template allows
* you to modify some parts of your layout easily.
*
* Note that you can replace an existing block and add new blocks at runtime.
* Adding new blocks means changing a variable placeholder to a block.
