APC, which is short for Alternative PHP Cache, is a framework used for caching the compiled source code of a given script application, that can boost a database-driven website several times. Each time a PHP web page is accessed, the script pulls the website content that has to be shown from a database, parses and compiles the code, and then the result is displayed to the site visitor. While this is necessary for Internet sites with regularly changing content, it's a total waste of processing time and system resources for an Internet site that doesn't change, like an informational portal that displays identical content on a regular basis. As soon as the webpages for such a site are compiled, APC caches them and delivers them any time a visitor opens them. As this saves the time to request content from the database and to parse and compile the program code, your Internet site will load much faster. APC is really useful in particular for scripts with larger source code.
APC (PHP Opcode Cache) in Semi-dedicated Hosting
You can take full advantage of APC with our semi-dedicated hosting packages and activating this framework is performed with a mouse click in the Hepsia Control Panel, so even if you have no previous experience, you can use it in order to quicken your sites. As the cloud hosting platform where the semi-dedicated accounts are created supports multiple PHP releases, you will have freedom with regards to the scripts and web accelerators you'll be able to use. It will take you only a click to enable APC for one or several PHP releases and by using a php.ini file in the domain/subdomain folders where you need settings that are different from the ones for the account in general, you will be able to set what PHP version will be used and whether APC should be allowed or not. This way, one site can use APC and PHP 5.3, for instance, whereas another one may use a different accelerator and PHP 5.5.
