APC, which stands for 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. Any time a PHP webpage is opened, the script pulls the site content which should be shown from a database, parses and compiles the code, then the result is shown to the website visitor. While this is necessary for websites with constantly changing content, it is a total waste of processing time and system resources for a site which doesn't change, for instance an informational portal which displays the exact same content all the time. As soon as the pages for such a site are compiled, APC caches them and delivers them whenever a user accesses them. As this saves the time to get content from the database and to parse and compile the code, the site will load considerably quicker. APC is very effective especially for scripts with large source code.
APC (PHP Opcode Cache) in Website Hosting
You'll be able to employ APC for your web applications with any of the website hosting packages that we offer since it is pre-installed on our cloud web hosting platform. Turning it on will take just a mouse click inside the Hepsia Control Panel which comes with our shared plans and a few minutes later it will begin caching the code of your software applications. Our platform is quite flexible, so you'll be able to use different configurations determined by the system requirements of the scripts. For instance, you can activate APC for several releases of PHP for the entire account and select the version that each Internet site can use, or you can have the very same version of PHP, but enable or disable APC just for specified Internet sites. You can do this by putting a php.ini file with a line of code within the domain or subdomain folder where you need the customized configuration.
