Guard Loader

The Zend Guard Loader is a PHP extension that runs PHP scripts encoded by Zend Guard, which provides an easy way to encode, obfuscate and license PHP code via an Eclipse-based interface or from the command line.

The Guard Loader extension must be installed on each Web server that runs files that were encoded with, or use, Zend Guard licenses.

Note:

You can also use the Zend Optimizer that also includes the Guard Loader extension for code written in PHP 5.2. The Zend Optimizer is available as a free download from www.zend.com.

The Zend Guard Loader translates encoded files to a format that can be parsed by the Zend Engine. This runtime process uses the Zend engine as a trigger to start the Zend Guard Loader component.
