Alternative PHP Cache

Alternative PHP Cache, commonly known as APC is a free opcode cache framework. It provides free and robust caching and optimizing options for PHP intermediate code. Apart from providing users with opcode cache, it also offers cache for storing application data. APC stores the PHP bytecode which eliminates the need for recompiling it every time whenever necessary, and this increases the performance of PHP. It also reduces parsing and disk I/O overhead for any further requests.
