If you use PHP 5.3 or later, you must use Zend Guard Loader instead of Zend Optimizer. For more information, see Using Zend Guard Loader.
To use Zend Optimizer with our hosting accounts, you must disable APC. For more information, see Disabling APC on Your Hosting Account.

php5.ini file. The file you create or modify must include the following code in the first line of your file:
Zend Optimizer might corrupt files encoded for Zend Guard Loader and PHP 5.3
We recommend backing up your
php5.ini file before modifying it.
