    APC or Alternative PHP Cache, is a free open-source opcode (operation code) caching plugin for PHP. With APC caching your PHP script executions can run more efficiently, by cutting down on dynamic PHP executions.

    In this article, you’ll learn how to speed up PHP with APC.

    Why would you want to install APC?

    PHP is a dynamic scripting language, so every time there is a request for a page, the server must first parse the code in your PHP script in order to generate the resulting HTML code seen by a visitor’s web-browser.

    PHP is ideal for web pages that have content that is constantly updated, since each visitor gets a fresh copy of the page. So for instance if you have your PHP script pulling data from a database, as soon as there is new data in the database, it will automatically be in the generated HTML code for the next visitor requesting that page as well.

    In most cases the need to re-run PHP scripts for data that might not have changed in the first place, can be taxing on the server. By implementing APC you cut down on repeat PHP script executions, skipping the parsing and compiling steps. APC stores the opcode, and that is simply executed each time the script is called again.

    What’s the difference between APC and other types of caching?

    APC for PHP is one of the most widely used PHP opcode caching solutions in use today. You can utilize APC on a VPS  or dedicated server that is running PHP as either DSO or FastCGI. You might want to read about choosing the best PHP handler for your specific needs, and also a more in-depth explanation on what DSO and FastCGI are.

    Another common caching module is Memcached, and the main difference between it and APC is that Memcached is distributed and more robust generic caching platform, while APC is specific to PHP. APC is great when you need local caching of objects for your PHP scripts that are relatively small and frequently accessed.

    How to install APC

    APC is a PECL module that can be loaded into PHP, but because it operates at the server-level it can not be run on our shared hosting servers. If you are on a VPS or dedicated server and are comfortable installing PECL modules, then you can go ahead and install APC yourself.

    Or if you prefer our system administration department can setup APC on your server for you. If this is something that you’d like to take advantage of please contact our support department.
