// 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

  // ----- 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', ' ' );

  // 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

  //   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.

  // Function : listContent()
  // Description :
  //   This public method, gives the list of the files and directories, with their
  //   properties.
  //   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
  //                                      directory with the same name already exists
  //                write_protected : the file can not be extracted because a file
  //                                  with the same name already exists and is
  //                                  write protected
  //                newer_exist : the file was not extracted because a newer file exists
  //                path_creation_fail : the file is not extracted because the folder
  //                                     does not exists and can not be created
  //                write_error : the file was not extracted because there was a
  //                              error while writing the file
  //                read_error : the file was not extracted because there was a error
  //                             while reading the file
  //                invalid_header : the file was not extracted because of an archive
  //                                 format error (bad file header)
  //   Note that each time a method can continue operating when there
  //   is an action error on a file, the error is only logged in the file status.
  // Return Values :
  //   0 on an unrecoverable failure,
  //   The list of the files in the archive.
