TbsZip

It will allow developers to zip/unzip archive files on the fly, using PHP code only.

Features:

• Read a common zip archive, or start with an empty archive
• Can modify the content of files in the archive (replace, delete or add new file)
• The new file content can come from a PHP string, or an external physical file
• The modified archive can be released as a new physical file, an HTTP download, or a PHP string
• The original archive is not modified
• The class does not use temporary files

What is new in this release:

• Bug fix:
• Could not download a file that has the same name as the opened archive.

Requirements:

Limitations:
