Failed loading /usr/sbin/ioncube_loader_lin_5.2.so: /usr/sbin/ioncube_loader_lin_5.2.so: undefined symbol: zend_error_noreturn
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.
