// Presentation :

//   PclZip is a PHP library that manage ZIP archives.

//   So far tests show that archives generated by PclZip are readable by

//   WinZip application and other tools.

//

// Description :

//   See readme.txt and http://www.phpconcept.net

//

// Warning :

//   This library and the associated files are non commercial, non professional

//   work.

//   It should not have unexpected results. However if any damage is caused by

//   this software the author can not be responsible.

//   The use of this software is at the risk of the user.

// ----- Constants

if (!defined('PCLZIP_READ_BLOCK_SIZE')) {

    define( 'PCLZIP_READ_BLOCK_SIZE', 2048 );

}



// ----- File list separator

// In version 1.x of PclZip, the separator for file list is a space

// (which is not a very smart choice, specifically for windows paths !).

// A better separator should be a comma (,). This constant gives you the

// abilty to change that.

// However notice that changing this value, may have impact on existing

// scripts, using space separated filenames.

// Recommanded values for compatibility with older versions :

//define( 'PCLZIP_SEPARATOR', ' ' );

// Recommanded values for smart separation of filenames.

if (!defined('PCLZIP_SEPARATOR')) {

    define( 'PCLZIP_SEPARATOR', ',' );

}



// ----- Error configuration

// 0 : PclZip Class integrated error handling

// 1 : PclError external library error handling. By enabling this

//     you must ensure that you have included PclError library.

// [2,...] : reserved for futur use

if (!defined('PCLZIP_ERROR_EXTERNAL')) {

    define( 'PCLZIP_ERROR_EXTERNAL', 0 );

}



// ----- Optional static temporary directory

//       By default temporary files are generated in the script current

//       path.

//       If defined :

//       - MUST BE terminated by a '/'.

//       - MUST be a valid, already created directory

//       Samples :

// define( 'PCLZIP_TEMPORARY_DIR', '/temp/' );

// define( 'PCLZIP_TEMPORARY_DIR', 'C:/Temp/' );

if (!defined('PCLZIP_TEMPORARY_DIR')) {

    define( 'PCLZIP_TEMPORARY_DIR', '' );

}



// ----- Optional threshold ratio for use of temporary files

//       Pclzip sense the size of the file to add/extract and decide to

//       use or not temporary file. The algorythm is looking for

//       memory_limit of PHP and apply a ratio.

//       threshold = memory_limit * ratio.

//       Recommended values are under 0.5. Default 0.47.

//       Samples :

// define( 'PCLZIP_TEMPORARY_FILE_RATIO', 0.5 );

    // Description :

    //   This method supports two different synopsis. The first one is historical.

    //   This method creates a Zip Archive. The Zip file is created in the

    //   filesystem. The files and directories indicated in $p_filelist

    //   are added in the archive. See the parameters description for the

    //   supported format of $p_filelist.

    //   When a directory is in the list, the directory and its content is added

    //   in the archive.

    //   In this synopsis, the function takes an optional variable list of

    //   options. See bellow the supported options.

    // Parameters :

    //   $p_filelist : An array containing file or directory names, or

    //                 a string containing one filename or one directory name, or

    //                 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

    //                   is removed first, before $p_add_dir is added.
