APC, or Alternative PHP Cache, is a PHP module which caches the output code of database-driven script applications. Dynamic PHP Internet sites save their content in a database that is accessed whenever a visitor loads a page. The content which needs to be viewed is retrieved and the code is parsed and compiled before it is delivered to the website visitor. These actions take some processing time and require reading and writing on the web server for every single page that is opened. While this can't be avoided for Internet sites with constantly changing content material, there are many websites which have the exact same content on many of their pages all the time - blogs, informational portals, hotel and restaurant Internet sites, and many others. APC is really useful for this kind of websites since it caches the already compiled code and shows it any time visitors browse the cached pages, so the code doesn't have to be parsed and compiled repeatedly. This will not only lower the server load, but it will also boost the speed of any site several times.
APC (PHP Opcode Cache) in Hosting
You can employ APC for your web applications with any of the hosting packages that we provide as it's pre-installed on our cloud web hosting platform. Activating it will take only a click inside the Hepsia Control Panel which comes with our shared plans and a couple of minutes later it will begin caching the code of your software applications. Our platform is very flexible, so you will be able to use several configurations based on the system requirements of your scripts. For instance, you can activate APC for several versions of PHP for the whole account and specify the version that each Internet site can use, or you could have the very same version of PHP, but activate or deactivate APC only for specified websites. You can do this by putting a php.ini file with a line of code inside the domain or subdomain folder where you need the customized setup.
