APC, which means Alternative PHP Cache, is a framework used for caching the compiled source code of a script app, that can boost a database-driven website several times. Every time a PHP web page is opened, the script pulls the content that needs to be displayed from a database, parses and compiles the program code, and then the result is displayed to the site visitor. While this is necessary for websites with regularly changing content, it's a total waste of processing time and resources for a site which does not change, for example an informational portal that displays the same content all the time. When the web pages for such an Internet site are compiled, APC caches them and delivers them whenever a website visitor opens them. As this saves the time to obtain content from the database and to parse and compile the program code, your website will load much faster. APC is really useful especially for scripts with larger source code.
APC (PHP Opcode Cache) in Semi-dedicated Hosting
You’ll be able to use APC for each script application which runs on your new semi-dedicated hosting as the module is already installed on the cloud hosting platform where the account will be created. Activating or deactivating APC for the whole account takes a single click inside the Hepsia Control Panel, but if needed, you can use the module only for specific Internet sites. This is possible due to the flexibility of our cloud platform - different versions of PHP run on it at the same time, so with a php.ini file placed in a site folder, you can choose what release will be used for this specific site and whether APC should be enabled or disabled. Employing such a file permits you to use settings which are different from the ones for your account, so you could take advantage of APC for many scripts where the module makes a difference and not for others where you may use a different kind of web accelerator.
