APC, which is an acronym for Alternative PHP Cache, is a framework used for caching the compiled source code of a script application, which can speed up a database-driven site several times. Each time a PHP page is accessed, the script pulls the website content that needs to be shown from a database, parses and compiles the program code, then the result is shown to the website visitor. While this is necessary for websites with constantly changing content, it is a waste of processing time and system resources for an Internet site that doesn't change, such as an informational portal that displays the exact same content on a regular basis. Once the webpages for such a site 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 code, the Internet site will load considerably faster. APC is really efficient particularly for scripts with massive source code.
APC (PHP Opcode Cache) in Cloud Website Hosting
You can employ APC for your web apps with all of the cloud website hosting packages that we offer because it is pre-installed on our cloud web hosting platform. Turning it on will take just a click inside the Hepsia Control Panel that comes with our shared solutions and several minutes later it'll start caching the code of your applications. Our platform is really flexible, so you will be able to use different configurations based on the system requirements of your scripts. For example, you could activate APC for several releases of PHP for the whole account and set the version that each Internet site will use, or you could have the same version of PHP, but activate or deactivate APC just for particular sites. You can do this by placing a php.ini file with a line of code within the domain or subdomain folder where you need the customized configuration.
