Using APC with PHP. Cache Cow If you’ve been around PHP for a while, you’ve probably heard about APC, the Alternative PHP Cache.
APC is an opcode cache that can significantly speed up your PHP applications, by caching both PHP code and user variables. Adding APC to an application usually results in improved application response times, reduced server load and happier users. In this article, I’ll introduce you to APC, guiding you through the process of installing and configuring it and showing you a few examples of how it works. I’ll also walk you through the APC administrator interface, which lets you view APC performance in real time, and show you how you can use it with the Zend Framework.
Getting Started First up, a quick description of what APC is and how it works. As you probably already know, PHP is an interpreted language (unlike, say, Java or C++). Does it work?

APC - Alternative PHP Cache. 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. Besides a opcode cache it provides a user cache for storing application data. This module uses the APC user cache as a cache backend for Drupal. Use APC for caches that do not change often and will not grow too big to avoid fragmentation. The default setting of APC will allow you to store 32 MiB for the opcode cache and the user cache combined. Drupal 6 The APC backend can be run for drupal 6 using cache backport.
