Zend error: The apc extension must be loaded for using this backend

Hi I am getting the above error setting up my Zend application on a publi开发者_运维技巧c hosted server. I have another application on the same sever which works ok so I assume APC is obviously loaded. How can I diagnose this? Thanks

I'm assuming you are you using the APC Zend_Cache backend. To use this, you need the APC extension installed.

To check if it is loaded, just paste the following into a php file and then view it in a browser:

<?php
phpinfo();

Search for the block that says something like "This program makes use of the Zend Scripting Language Engine: Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies"

If you see APC in there, then it's loaded.

Check for "apc" extension.
