After upgrading PHP recently on a CentOS Linux server from PHP 5.2.X to PHP 5.3.X I ran into numerous minor issues. One of the issues was with a web application that requires the ionCube PHP Encoder libraries to function properly. After upgrading PHP I noticed some errors in the Apache error logs including the ionCube Apache module that was failing to load. Below I display the entire error from the Apache error_log file and how to easily resolve the issue by installing a single package via the Yum Package Manager.

After the package is installed you should restart your web server for the changes to take. In this example the server is running Apache which can be restarted using the below command example.
Restart Apache For The ionCube Module To Load:
- [root@dev ~]# /etc/init.d/httpd restart
- Stopping httpd: [ OK ]
- Starting httpd: [ OK ]
- [root@dev ~]#
The ionCube loader error should no longer appear in the Apache error logs.
