TbsZip - a zip modifier and creator

This class can be used to modify or create a ZIP archive in pure PHP, without need of temporary files.

TbsZip can list, add, delete, replace files that are contained in an archive. The new content of a file can either come from a PHP string (binary string as well as text string), or from a physical external file.

The original archive is not modified. The modified archive can be provided as a new physical file, an HTTP download, or a binary string.

Any files in the archive can be extracted, but the contents of a file can be compressed or uncompressed since the ZLib extension is available. compression and uncompression is then automatic.
