APC, or Alternative PHP Cache, is a PHP module that caches the output code of database-driven script apps. Dynamic PHP Internet sites save their content in a database that is accessed whenever a visitor loads a webpage. The content that needs to be displayed is gathered and the code is parsed and compiled before it is delivered to the visitor. All of these actions take some processing time and require reading and writing on the hosting server for each page that is loaded. While this cannot be avoided for sites with regularly changing content, there are numerous Internet sites that present the exact same content on a number of of their pages all the time - blogs, informational portals, hotel and restaurant websites, etcetera. APC is really useful for this kind of sites as it caches the previously compiled code and shows it each time visitors browse the cached webpages, so the code doesn't have to be parsed and compiled all over again. This will not only reduce the server load, but it'll also boost the speed of any site a few times.
APC (PHP Opcode Cache) in Semi-dedicated Servers
You can use APC with all our semi-dedicated server plans and activating this framework is done with a click inside the Hepsia Control Panel, so even if you lack previous experience, you'll be able to use it in order to accelerate your websites. As the cloud hosting platform where the semi-dedicated accounts are created is compatible with multiple PHP releases, you will have flexibility with regards to the scripts and web accelerators you could employ. It will take you only a click to activate APC for one or a couple of PHP versions and by using a php.ini file inside the domain/subdomain folders where you need settings which are different from the ones for the account in general, you'll be able to set what PHP release will be used and whether APC needs to be allowed or not. In this way, one site may use APC and PHP 5.3, for instance, and another one can use some different accelerator and PHP 5.5.
