|
// 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 |

// Parameters : |

|
// 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 |
