// 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')) {

  }



  // ----- 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.

  // define( 'PCLZIP_TEMPORARY_FILE_RATIO', 0.5 );

  // Description :

  //   PclZip is the class that represent a Zip archive.

  //   The public methods allow the manipulation of the archive.

  // Attributes :

  //   Attributes must not be accessed directly.

  // Methods :

  //   PclZip() : Object creator

  //   create() : Creates the Zip archive

  //   listContent() : List the content of the Zip archive

  //   extract() : Extract the content of the archive

  //   properties() : List the properties of the archive

  // --------------------------------------------------------------------------------

    // ----- Current status of the magic_quotes_runtime

    // This value store the php configuration for magic_quotes

    // The class can then disable the magic_quotes and reset it after

    var $magic_quotes_status;



  // --------------------------------------------------------------------------------

  // Function : PclZip()

  // Description :

  //   Creates a PclZip object and set the name of the associated Zip archive

  //   filename.

  //   Note that no real action is taken, if the archive does not exist it is not

  //   created. Use create() for that.

  // Function :

  //   create($p_filelist, $p_add_dir="", $p_remove_dir="")

  //   create($p_filelist, $p_option, $p_option_value, ...)

  // 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.

  // Options :

  //   PCLZIP_OPT_ADD_PATH :

  //   PCLZIP_OPT_REMOVE_PATH :

  //   PCLZIP_OPT_REMOVE_ALL_PATH :

  //   PCLZIP_OPT_COMMENT :

  //   PCLZIP_CB_PRE_ADD :

  //   PCLZIP_CB_POST_ADD :

  // Return Values :

  //   0 on failure,

  //   The list of the added files, with a status of the add action.

  //   (see PclZip::listContent() for list entry format)

  //   The properties of each entries in the list are (used also in other functions) :

  //     filename : Name of the file. For a create or add action it is the filename

  //                given by the user. For an extract function it is the filename

  //                of the extracted file.

  //     stored_filename : Name of the file / directory stored in the archive.

  //     size : Size of the stored file.

  //     compressed_size : Size of the file's data compressed in the archive

  //                       (without the headers overhead)

  //     mtime : Last known modification date of the file (UNIX timestamp)

  //     comment : Comment associated with the file

  //     folder : true | false

  //     index : index of the file in the archive

  //     status : status of the action (depending of the action) :

  //              Values are :

  //                ok : OK !

  //                filtered : the file / dir is not extracted (filtered by user)

  //                already_a_directory : the file can not be extracted because a

  //                write_protected : the file can not be extracted because a file

  //                write_error : the file was not extracted because there was a
