Installation Of ZendOptimizer And IonCubeLoader Using Lighttpd On CentOS

This tutorial explains how to enable ZendOptimizer and IonCubeLoader in PHP on a Lighttpd web server on CentOS.


What is Ioncube Loader?

IonCube loader is the PHP extension that decodes encrypted PHP files on runtime. It is freely available and installation is very easy.


What is Zend Optimizer?

The Zend Optimizer is a free runtime application that enables PHP to run the files encoded by the Zend Guard. This can be freely used by anyone looking to run encoded applications. Please download and follow the installation instructions included in the distributions.
