  10  //   PclZip is a PHP library that manage ZIP archives.
  11  //   So far tests show that archives generated by PclZip are readable by
  12  //   WinZip application and other tools.
  13  //
  14  // Description :
  15  //   See readme.txt and http://www.phpconcept.net
  16  //

 244    //   supported format of $p_filelist.

 246    //   in the archive.

 248    //   options. See bellow the supported options.

 250    //   $p_filelist : An array containing file or directory names, or
 251    //                 a string containing one filename or one directory name, or

 253    //                 names separated by spaces.
 254    //   $p_add_dir : A path to add before the real path of the archived file,
 255    //                in order to have it memorized in the archive.
 256    //   $p_remove_dir : A path to remove from the real path of the file to archive,
 257    //                   in order to have a shorter path memorized in the archive.
 258    //                   When $p_add_dir and $p_remove_dir are set, $p_remove_dir
