APC, which means Alternative PHP Cache, is a framework used for caching the compiled source code of a script app, that could speed up a database-driven website several times. Every time a PHP webpage is accessed, the script pulls the website content that needs to be displayed from a database, parses and compiles the code, and then the result is shown to the site visitor. While this is necessary for sites with constantly changing content, it is a complete waste of processing time and system resources for a website which doesn't change, for example an informational portal which shows identical content on a regular basis. Once the web pages for such a website are compiled, APC caches them and delivers them each time a visitor loads them. As this saves the time to collect content from the database and to parse and compile the code, the website will load much quicker. APC is really efficient especially for scripts with massive source code.
APC (PHP Opcode Cache) in Semi-dedicated Hosting
APC is available with all semi-dedicated hosting plans as it's pre-installed on the cloud website hosting platform where your account shall be created. In case you wish to use this module, you'll be able to activate it with just a single click from your Hepsia Control Panel and it will be fully functional within a couple of minutes. Since you may need to use some other web accelerators for selected websites, our state-of-the-art platform will enable you to customize the software environment in your account. You will be able to activate APC for different versions of PHP or use it just for some websites and not for others. For instance, a Drupal™-based site could work with APC using PHP 5.4 and a WordPress website can work without APC employing PHP 5.6. What is needed to do that is a php.ini file with a few lines in it, so you can run sites with different requirements in the same account.
