- *
- * For an m-by-n matrix A with m >= n, the LU decomposition is an m-by-n
- * unit lower triangular matrix L, an n-by-n upper triangular matrix U,
- * and a permutation vector piv of length m so that A(piv,:) = L*U.
- * If m < n, then L is m-by-m and U is m-by-n.
- *
- * The LU decompostion with pivoting always exists, even if the matrix is
- * singular, so the constructor will never fail. The primary use of the
- * LU decomposition is in the solution of square systems of simultaneous
- * linear equations. This will fail if isNonsingular() returns false.

-* A class to calculate descriptive statistics from a data set.

-* <pre>
-* $data1 = array (1,2,1,1,1,1,3,3,4.1,3,2,2,4.1,1,1,2,3,3,2,2,1,1,2,2);

-* can be epxressed more compactly as:
-*
-* <pre>
-* $data2 = array('1'=>9, '2'=>8, '3'=>5, '4.1'=>2);
-* </pre>
-*
-* Example of use:
-*
-* <pre>
-* include_once 'Math/Stats.php';
-* $s = new Math_Stats();
-* $s->setData($data1);
-* // or
-* // $s->setData($data2, STATS_DATA_CUMMULATIVE);
-* $stats = $s->calcBasic();
-* echo 'Mean: '.$stats['mean'].' StDev: '.$stats['stdev'].' <br />\n';
-*
-* // using data with nulls
-* // first ignoring them:
-* $data3 = array(1.2, 'foo', 2.4, 3.1, 4.2, 3.2, null, 5.1, 6.2);
-* $s->setNullOption(STATS_IGNORE_NULL);
-* $s->setData($data3);
-* $stats3 = $s->calcFull();
-*
-* // and then assuming nulls == 0
-* $s->setNullOption(STATS_USE_NULL_AS_ZERO);

- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[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.
-
- <one line to give the library's name and a brief idea of what it does.>
- Copyright (C) <year> <name of author>
-
- 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. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the
- library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
- <signature of Ty Coon>, 1 April 1990
- Ty Coon, President of Vice
-
-That's all there is to it!

- // a string containing a list of filenames and/or directory
- // names separated by spaces.
- // $p_add_dir : A path to add before the real path of the archived file,
- // in order to have it memorized in the archive.
- // $p_remove_dir : A path to remove from the real path of the file to archive,
- // in order to have a shorter path memorized in the archive.
- // When $p_add_dir and $p_remove_dir are set, $p_remove_dir

-1 - Introduction
-================
-
- PclZip is a library that allow you to manage a Zip archive.
-
- Full documentation about PclZip can be found here : http://www.phpconcept.net/pclzip
-
-2 - What's new
-==============
-
- Version 2.8.2 :
- - PCLZIP_CB_PRE_EXTRACT and PCLZIP_CB_POST_EXTRACT are now supported with
- extraction as a string (PCLZIP_OPT_EXTRACT_AS_STRING). The string
- can also be modified in the post-extract call back.
- **Bugs correction :
- - PCLZIP_OPT_REMOVE_ALL_PATH was not working correctly
- - Remove use of eval() and do direct call to callback functions
- - Correct support of 64bits systems (Thanks to WordPress team)
-
- Version 2.8.1 :
- - Move option PCLZIP_OPT_BY_EREG to PCLZIP_OPT_BY_PREG because ereg() is
- deprecated in PHP 5.3. When using option PCLZIP_OPT_BY_EREG, PclZip will
- automatically replace it by PCLZIP_OPT_BY_PREG.
-
- Version 2.8 :
- - Improve extraction of zip archive for large files by using temporary files
- This feature is working like the one defined in r2.7.
- Options are renamed : PCLZIP_OPT_TEMP_FILE_ON, PCLZIP_OPT_TEMP_FILE_OFF,
- PCLZIP_OPT_TEMP_FILE_THRESHOLD
- - Add a ratio constant PCLZIP_TEMPORARY_FILE_RATIO to configure the auto
- sense of temporary file use.
- - Bug correction : Reduce filepath in returned file list to remove ennoying
- './/' preambule in file path.
-
- Version 2.7 :
- - Improve creation of zip archive for large files :
- PclZip will now autosense the configured memory and use temporary files
- when large file is suspected.
- This feature can also ne triggered by manual options in create() and add()
- methods. 'PCLZIP_OPT_ADD_TEMP_FILE_ON' force the use of temporary files,
- 'PCLZIP_OPT_ADD_TEMP_FILE_OFF' disable the autosense technic,
- 'PCLZIP_OPT_ADD_TEMP_FILE_THRESHOLD' allow for configuration of a size
- threshold to use temporary files.
- Using "temporary files" rather than "memory" might take more time, but
- might give the ability to zip very large files :
- Tested on my win laptop with a 88Mo file :
- Zip "in-memory" : 18sec (max_execution_time=30, memory_limit=180Mo)
- Zip "tmporary-files" : 23sec (max_execution_time=30, memory_limit=30Mo)
- - Replace use of mktime() by time() to limit the E_STRICT error messages.
- - Bug correction : When adding files with full windows path (drive letter)
- PclZip is now working. Before, if the drive letter is not the default
- path, PclZip was not able to add the file.
-
- Version 2.6 :
- - Code optimisation
- - New attributes PCLZIP_ATT_FILE_COMMENT gives the ability to
- add a comment for a specific file. (Don't really know if this is usefull)
- - New attribute PCLZIP_ATT_FILE_CONTENT gives the ability to add a string
- as a file.
- - New attribute PCLZIP_ATT_FILE_MTIME modify the timestamp associated with
- a file.
- - Correct a bug. Files archived with a timestamp with 0h0m0s were extracted
- with current time
- - Add CRC value in the informations returned back for each file after an
- action.
- - Add missing closedir() statement.
- - When adding a folder, and removing the path of this folder, files were
- incorrectly added with a '/' at the beginning. Which means files are
- related to root in unix systems. Corrected.
- - Add conditional if before constant definition. This will allow users
- to redefine constants without changing the file, and then improve
- upgrade of pclzip code for new versions.
-
- Version 2.5 :
- - Introduce the ability to add file/folder with individual properties (file descriptor).
- This gives for example the ability to change the filename of a zipped file.
- . Able to add files individually
- . Able to change full name
- . Able to change short name
- . Compatible with global options
- - New attributes : PCLZIP_ATT_FILE_NAME, PCLZIP_ATT_FILE_NEW_SHORT_NAME, PCLZIP_ATT_FILE_NEW_FULL_NAME
- - New error code : PCLZIP_ERR_INVALID_ATTRIBUTE_VALUE
- - Add a security control feature. PclZip can extract any file in any folder
- of a system. People may use this to upload a zip file and try to override
- a system file. The PCLZIP_OPT_EXTRACT_DIR_RESTRICTION will give the
- ability to forgive any directory transversal behavior.
- - New PCLZIP_OPT_EXTRACT_DIR_RESTRICTION : check extraction path
- - New error code : PCLZIP_ERR_DIRECTORY_RESTRICTION
- - Modification in PclZipUtilPathInclusion() : dir and path beginning with ./ will be prepend
- by current path (getcwd())
-
- Version 2.4 :
- - Code improvment : try to speed up the code by removing unusefull call to pack()
- - Correct bug in delete() : delete() should be called with no argument. This was not
- the case in 2.3. This is corrected in 2.4.
- - Correct a bug in path_inclusion function. When the path has several '../../', the
- result was bad.
- - Add a check for magic_quotes_runtime configuration. If enabled, PclZip will
- disable it while working and det it back to its original value.
- This resolve a lots of bad formated archive errors.
- - Bug correction : PclZip now correctly unzip file in some specific situation,
- when compressed content has same size as uncompressed content.
- - Bug correction : When selecting option 'PCLZIP_OPT_REMOVE_ALL_PATH',
- directories are not any more created.
- - Code improvment : correct unclosed opendir(), better handling of . and .. in
- loops.
-
-
- Version 2.3 :
- - Correct a bug with PHP5 : affecting the value 0xFE49FFE0 to a variable does not
- give the same result in PHP4 and PHP5 ....
-
- Version 2.2 :
- - Try development of PCLZIP_OPT_CRYPT .....
- However this becomes to a stop. To crypt/decrypt I need to multiply 2 long integers,
- the result (greater than a long) is not supported by PHP. Even the use of bcmath
- functions does not help. I did not find yet a solution ...;
- - Add missing '/' at end of directory entries
- - Check is a file is encrypted or not. Returns status 'unsupported_encryption' and/or
- error code PCLZIP_ERR_UNSUPPORTED_ENCRYPTION.
- - Corrected : Bad "version need to extract" field in local file header
- - Add private method privCheckFileHeaders() in order to check local and central
- file headers. PclZip is now supporting purpose bit flag bit 3. Purpose bit flag bit 3 gives
- the ability to have a local file header without size, compressed size and crc filled.
- - Add a generic status 'error' for file status
- - Add control of compression type. PclZip only support deflate compression method.
- Before v2.2, PclZip does not check the compression method used in an archive while
- extracting. With v2.2 PclZip returns a new error status for a file using an unsupported
- compression method. New status is "unsupported_compression". New error code is
- PCLZIP_ERR_UNSUPPORTED_COMPRESSION.
- - Add optional attribute PCLZIP_OPT_STOP_ON_ERROR. This will stop the extract of files
- when errors like 'a folder with same name exists' or 'a newer file exists' or
- 'a write protected file' exists, rather than set a status for the concerning file
- and resume the extract of the zip.
- - Add optional attribute PCLZIP_OPT_REPLACE_NEWER. This will force, during an extract' the
- replacement of the file, even if a newer version of the file exists.
- Note that today if a file with the same name already exists but is older it will be
- replaced by the extracted one.
- - Improve PclZipUtilOption()
- - Support of zip archive with trailing bytes. Before 2.2, PclZip checks that the central
- directory structure is the last data in the archive. Crypt encryption/decryption of
- zip archive put trailing 0 bytes after decryption. PclZip is now supporting this.
-
- Version 2.1 :
- - Add the ability to abort the extraction by using a user callback function.
- The user can now return the value '2' in its callback which indicates to stop the
- extraction. For a pre call-back extract is stopped before the extration of the current
- file. For a post call back, the extraction is stopped after.
- - Add the ability to extract a file (or several files) directly in the standard output.
- This is done by the new parameter PCLZIP_OPT_EXTRACT_IN_OUTPUT with method extract().
- - Add support for parameters PCLZIP_OPT_COMMENT, PCLZIP_OPT_ADD_COMMENT,
- PCLZIP_OPT_PREPEND_COMMENT. This will create, replace, add, or prepend comments
- in the zip archive.
- - When merging two archives, the comments are not any more lost, but merged, with a
- blank space separator.
- - Corrected bug : Files are not deleted when all files are asked to be deleted.
- - Corrected bug : Folders with name '0' made PclZip to abort the create or add feature.
-
-
- Version 2.0 :
- ***** Warning : Some new features may break the backward compatibility for your scripts.
- Please carefully read the readme file.
- - Add the ability to delete by Index, name and regular expression. This feature is
- performed by the method delete(), which uses the optional parameters
- PCLZIP_OPT_BY_INDEX, PCLZIP_OPT_BY_NAME, PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG.
- - Add the ability to extract by regular expression. To extract by regexp you must use the method
- extract(), with the option PCLZIP_OPT_BY_EREG or PCLZIP_OPT_BY_PREG
- (depending if you want to use ereg() or preg_match() syntax) followed by the
- regular expression pattern.
- - Add the ability to extract by index, directly with the extract() method. This is a
- code improvment of the extractByIndex() method.
- - Add the ability to extract by name. To extract by name you must use the method
- extract(), with the option PCLZIP_OPT_BY_NAME followed by the filename to
- extract or an array of filenames to extract. To extract all a folder, use the folder
- name rather than the filename with a '/' at the end.
- - Add the ability to add files without compression. This is done with a new attribute
- which is PCLZIP_OPT_NO_COMPRESSION.
- - Add the attribute PCLZIP_OPT_EXTRACT_AS_STRING, which allow to extract a file directly
- in a string without using any file (or temporary file).
- - Add constant PCLZIP_SEPARATOR for static configuration of filename separators in a single string.
- The default separator is now a comma (,) and not any more a blank space.
- THIS BREAK THE BACKWARD COMPATIBILITY : Please check if this may have an impact with
- your script.
- - Improve algorythm performance by removing the use of temporary files when adding or
- extracting files in an archive.
- - Add (correct) detection of empty filename zipping. This can occurs when the removed
- path is the same
- as a zipped dir. The dir is not zipped (['status'] = filtered), only its content.
- - Add better support for windows paths (thanks for help from manus@manusfreedom.com).
- - Corrected bug : When the archive file already exists with size=0, the add() method
- fails. Corrected in 2.0.
- - Remove the use of OS_WINDOWS constant. Use php_uname() function rather.
- - Control the order of index ranges in extract by index feature.
- - Change the internal management of folders (better handling of internal flag).
-
-
- Version 1.3 :
- - Removing the double include check. This is now done by include_once() and require_once()
- PHP directives.
- - Changing the error handling mecanism : Remove the use of an external error library.
- The former PclError...() functions are replaced by internal equivalent methods.
- By changing the environment variable PCLZIP_ERROR_EXTERNAL you can still use the former library.
- Introducing the use of constants for error codes rather than integer values. This will help
- in futur improvment.
- Introduction of error handling functions like errorCode(), errorName() and errorInfo().
- - Remove the deprecated use of calling function with arguments passed by reference.
- - Add the calling of extract(), extractByIndex(), create() and add() functions
- with variable options rather than fixed arguments.
- - Add the ability to remove all the file path while extracting or adding,
- without any need to specify the path to remove.
- This is available for extract(), extractByIndex(), create() and add() functionS by using
- the new variable options parameters :
- - PCLZIP_OPT_REMOVE_ALL_PATH : by indicating this option while calling the fct.
- - Ability to change the mode of a file after the extraction (chmod()).
- This is available for extract() and extractByIndex() functionS by using
- the new variable options parameters.
- - PCLZIP_OPT_SET_CHMOD : by setting the value of this option.
- - Ability to definition call-back options. These call-back will be called during the adding,
- or the extracting of file (extract(), extractByIndex(), create() and add() functions) :
- - PCLZIP_CB_PRE_EXTRACT : will be called before each extraction of a file. The user
- can trigerred the change the filename of the extracted file. The user can triggered the
- skip of the extraction. This is adding a 'skipped' status in the file list result value.
- - PCLZIP_CB_POST_EXTRACT : will be called after each extraction of a file.
- Nothing can be triggered from that point.
- - PCLZIP_CB_PRE_ADD : will be called before each add of a file. The user
- can trigerred the change the stored filename of the added file. The user can triggered the
- skip of the add. This is adding a 'skipped' status in the file list result value.
- - PCLZIP_CB_POST_ADD : will be called after each add of a file.
- Nothing can be triggered from that point.
- - Two status are added in the file list returned as function result : skipped & filename_too_long
- 'skipped' is used when a call-back function ask for skipping the file.
- 'filename_too_long' is used while adding a file with a too long filename to archive (the file is
- not added)
- - Adding the function PclZipUtilPathInclusion(), that check the inclusion of a path into
- a directory.
- - Add a check of the presence of the archive file before some actions (like list, ...)
- - Add the initialisation of field "index" in header array. This means that by
- default index will be -1 when not explicitly set by the methods.
-
- Version 1.2 :
- - Adding a duplicate function.
- - Adding a merge function. The merge function is a "quick merge" function,
- it just append the content of an archive at the end of the first one. There
- is no check for duplicate files or more recent files.
- - Improve the search of the central directory end.
-
- Version 1.1.2 :
-
- - Changing the license of PclZip. PclZip is now released under the GNU / LGPL license
- (see License section).
- - Adding the optional support of a static temporary directory. You will need to configure
- the constant PCLZIP_TEMPORARY_DIR if you want to use this feature.
- - Improving the rename() function. In some cases rename() does not work (different
- Filesystems), so it will be replaced by a copy() + unlink() functions.
-
- Version 1.1.1 :
-
- - Maintenance release, no new feature.
-
- Version 1.1 :
-
- - New method Add() : adding files in the archive
- - New method ExtractByIndex() : partial extract of the archive, files are identified by
- their index in the archive
- - New method DeleteByIndex() : delete some files/folder entries from the archive,
- files are identified by their index in the archive.
- - Adding a test of the zlib extension presence. If not present abort the script.
-
- Version 1.0.1 :
-
- - No new feature
-
-
-3 - Corrected bugs
-==================
-
- Corrected in Version 2.0 :
- - Corrected : During an extraction, if a call-back fucntion is used and try to skip
- a file, all the extraction process is stopped.
-
- Corrected in Version 1.3 :
- - Corrected : Support of static synopsis for method extract() is broken.
- - Corrected : invalid size of archive content field (0xFF) should be (0xFFFF).
- - Corrected : When an extract is done with a remove_path parameter, the entry for
- the directory with exactly the same path is not skipped/filtered.
- - Corrected : extractByIndex() and deleteByIndex() were not managing index in the
- right way. For example indexes '1,3-5,11' will only extract files 1 and 11. This
- is due to a sort of the index resulting table that puts 11 before 3-5 (sort on
- string and not interger). The sort is temporarilly removed, this means that
- you must provide a sorted list of index ranges.
-
- Corrected in Version 1.2 :
-
- - Nothing.
-
- Corrected in Version 1.1.2 :
-
- - Corrected : Winzip is unable to delete or add new files in a PclZip created archives.
-
- Corrected in Version 1.1.1 :
-
- - Corrected : When archived file is not compressed (0% compression), the
- extract method fails.
-
- Corrected in Version 1.1 :
-
- - Corrected : Adding a complete tree of folder may result in a bad archive
- creation.
-
- Corrected in Version 1.0.1 :
-
- - Corrected : Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024).
-
-
-4 - Known bugs or limitations
-=============================
-
- Please publish bugs reports in SourceForge :
- http://sourceforge.net/tracker/?group_id=40254&atid=427564
-
- In Version 2.x :
- - PclZip does only support file uncompressed or compressed with deflate (compression method 8)
- - PclZip does not support password protected zip archive
- - Some concern were seen when changing mtime of a file while archiving.
- Seems to be linked to Daylight Saving Time (PclTest_changing_mtime).
-
- In Version 1.2 :
-
- - merge() methods does not check for duplicate files or last date of modifications.
-
- In Version 1.1 :
-
- - Limitation : Using 'extract' fields in the file header in the zip archive is not supported.
- - WinZip is unable to delete a single file in a PclZip created archive. It is also unable to
- add a file in a PclZip created archive. (Corrected in v.1.2)
-
- In Version 1.0.1 :
-
- - Adding a complete tree of folder may result in a bad archive
- creation. (Corrected in V.1.1).
- - Path given to methods must be in the unix format (/) and not the Windows format (\).
- Workaround : Use only / directory separators.
- - PclZip is using temporary files that are sometime the name of the file with a .tmp or .gz
- added suffix. Files with these names may already exist and may be overwritten.
- Workaround : none.
- - PclZip does not check if the zlib extension is present. If it is absent, the zip
- file is not created and the lib abort without warning.
- Workaround : enable the zlib extension on the php install
-
- In Version 1.0 :
-
- - Error while compressing files greater than PCLZIP_READ_BLOCK_SIZE (default=1024).
- (Corrected in v.1.0.1)
- - Limitation : Multi-disk zip archive are not supported.
