Alternative PHP Cache, or APC, is a module for Apache servers which is used to cache the output code of script applications. It is very efficient for scripts with large source code and can accelerate such a website up to three times. PHP sites are dynamic and each time a user accesses some web page, the script links to a database to get some content, and then the code is parsed and compiled prior to it being displayed to the website visitor. In case the output code does not change however, that's the case with Internet sites which display the very same content all the time, these actions result in unneeded reading and writing. What APC does is that it caches the already compiled program code and delivers it every time visitors browse a website, so the database doesn't need to be accessed and the code does not need to be parsed and compiled repeatedly, that consequently minimizes the Internet site loading time. The module could be quite helpful for informational websites, blogs, portfolios, etcetera.
APC (PHP Opcode Cache) in Semi-dedicated Servers
You can take advantage of APC with all of our semi-dedicated server plans and activating the framework is performed with a mouse click in the Hepsia Control Panel, so even when you don't have any prior experience, you could use it to speed up your Internet sites. As the cloud hosting platform where the semi-dedicated accounts are made is compatible with multiple PHP releases, you'll have flexibility regarding the scripts and web accelerators you could employ. It will take you just a click to activate APC for one or a couple of PHP releases and by using a php.ini file inside 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 release will be used and whether APC should be allowed or not. In this way, one site can use APC and PHP 5.3, for instance, while another one can use some other accelerator and PHP 5.5.
