APC, which means Alternative PHP Cache, is a framework used for caching the compiled source code of a script app, that could boost a database-driven website several times. Every time a PHP web page is opened, the script pulls the website content that should be loaded from a database, parses and compiles the code, and the result is shown to the site visitor. While this is necessary for websites with frequently changing content, it's a complete waste of processing time and resources for a website that does not change, for example an informational portal that shows the very same content all the time. Once the pages for such a website are compiled, APC caches them and delivers them whenever a website visitor opens them. Since this saves the time to collect content from the database and to parse and compile the program code, your Internet site will load considerably faster. APC is really effective in particular for scripts with large source code.
APC (PHP Opcode Cache) in Web Hosting
APC is pre-installed on our state-of-the-art cloud platform, therefore you will be able to use it for your web applications regardless of the web hosting plan that you select when you register. The module can be enabled from the Hepsia hosting Control Panel that is used to maintain the shared accounts and only a couple of minutes later it'll speed up your sites as it will start caching their code. In case you need to run sites with various system requirements or employ specific web accelerators for some of them, you could customize the software environment by putting a php.ini file inside the desired domain folder. This way, you could enable or disable APC not only for a particular Internet site without affecting the remaining Internet sites in the account, but also for a certain version of PHP since our platform supports multiple versions at the same time.
