// 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 below 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 :
