APC, or Alternative PHP Cache, is a PHP module which caches the output code of database-driven script software applications. Dynamic PHP websites save their content in a database that is accessed whenever a visitor loads a webpage. The content which needs to be shown is retrieved and the code is parsed and compiled before it is delivered to the site visitor. These actions need some processing time and include reading and writing on the server for every single page that is opened. While this can't be avoided for sites with constantly changing content material, there're numerous Internet sites which feature the very same content on a number of of their webpages constantly - blogs, info portals, hotel and restaurant sites, etc. APC is very useful for such Internet sites because it caches the previously compiled code and displays it when visitors browse the cached webpages, so the code does not need to be parsed and compiled repeatedly. This will not only greatly reduce the server load, but it'll also boost the speed of any site several times.
APC (PHP Opcode Cache) in Semi-dedicated Hosting
APC is set up on the state-of-the-art cloud Internet hosting platform where all semi-dedicated hosting accounts are created, so you will be able to employ it regardless of the plan you get. Activating the module is performed from the Hepsia Control Panel and takes only a click, so you will not need any skills or previous experience to be able to take advantage of it. As you'll be able to work with several releases of PHP at the same time, you will be able to modify the software environment for each website you host in the account if necessary. A php.ini file with a few lines in it placed in a domain folder will enable you to set what release of PHP this particular website will use and if APC has to be on or off for it. These settings will have priority over the ones for the account as a whole, so you could run various scripts and employ various web accelerators for websites that are in the same account.
