Zend Guard is a product to protect PHP source code. We use it for our evaluation versions and some old versions of our products. The PHP code will get pre-compiled and encrypted and a separate PHP module is required to load it: The Zend Guard Loader.
It can be download from here for free.
Sadly Zend doesn't care much about backwards compatiblity what results in the fact that a separate loader and software package for each PHP version is required. Because of this and other incidents we only supported zended Packages up to PHP 5.3.
