TbsZip is a PHP class that enables you to read and write Zip archives. The class doesn't require PHP extensions or temporary files. TbsZip can read, add, delete, and modify files stored in an archive. It can even start with an empty archive. The original archive is not modified. The new archive can be saved in the server as a new file, or provided directly as an HTTP download, or even as a binary string. If the Zlib extension is activated in PHP, then TbsZip can automatically compress and uncompress files in the archive.
