APC, or Alternative PHP Cache, is a PHP module that caches the output code of database-driven script apps. Dynamic PHP websites hold their content in a database that is accessed whenever a visitor loads a webpage. The content which needs to be shown is gathered and the code is parsed and compiled before it is delivered to the visitor. All of these actions need some processing time and include reading and writing on the web server for every single page which is loaded. While this cannot be avoided for sites with constantly changing content material, there are a lot of websites which offer the exact same content on many of their webpages all of the time - blogs, informational portals, hotel and restaurant sites, etcetera. APC is quite useful for such websites since it caches the previously compiled code and displays it any time visitors browse the cached pages, so the code doesn't have to be parsed and compiled again. Not only will this greatly reduce the server load, but it'll also boost the speed of any Internet site several times.
APC (PHP Opcode Cache) in Semi-dedicated Servers
You will be able to use APC for each and every script application that runs on your new semi-dedicated server as the module is already installed on the cloud hosting platform where the account will be made. Activating or deactivating APC for the whole account takes a single click in the Hepsia Control Panel, but if needed, you could use the module only for certain Internet sites. This is possible on account of the versatility of our cloud platform - multiple releases of PHP run on it simultaneously, so with a php.ini file placed in a site folder, you will be able to choose what version will be used for this specific website and whether APC should be enabled or disabled. Employing such a file permits you to use settings which are different from the ones for the account, so you will be able to take advantage of APC for many scripts where the module makes a difference and not for others where you can take advantage of a different kind of web accelerator.
