Description
The Alternative PHP Cache (APC) is a free and open opcode cache for PHP. Its goal is to provide a free, open, and robust framework for caching and optimizing PHP intermediate code. The installer comes with a small php script (apc.php) which gives you some useful info about APC. This script should not be available on production system as it may expose sensitive information.
