APC, or Alternative PHP Cache, is a PHP module that caches the output code of database-driven script applications. Dynamic PHP Internet sites store their content inside a database which is accessed whenever a visitor opens a page. The content which has to be displayed is retrieved and the code is parsed and compiled before it's delivered to the site visitor. All of these actions need some processing time and involve reading and writing on the web server for every single page which is accessed. While this cannot be avoided for Internet sites with constantly changing content, there are many sites that offer the very same content on a lot of of their pages all of the time - blogs, informational portals, hotel and restaurant sites, and many others. APC is very useful for this kind of websites as it caches the already compiled code and displays it whenever visitors browse the cached webpages, so the code doesn't need to be parsed and compiled repeatedly. Not only will this greatly reduce the server load, but it'll also raise the speed of any Internet site many times.
APC (PHP Opcode Cache) in Hosting
You will be able to employ APC for your web applications with all of the hosting
packages that we offer as it is pre-installed on our cloud web hosting platform. Turning it on will take only a mouse click inside the Hepsia Control Panel which is provided with our shared solutions and a couple of minutes later it'll start caching the program code of your apps. Our platform is very flexible, so you'll be able to use several configurations determined by the system requirements of the scripts. For instance, you'll be able to activate APC for several versions of PHP for the entire account and set the version that each Internet site will use, or you could have the very same version of PHP, but enable or disable APC just for specific Internet sites. You can do this by putting a php.ini file with a line of program code inside the domain or subdomain folder where you need the custom setup.
APC (PHP Opcode Cache) in Semi-dedicated Servers
APC is installed on the amazing cloud web hosting platform where all semi-dedicated server
accounts are created, so you will be able to employ it irrespective of the package you choose. Activating the module is performed from the Hepsia Control Panel and takes only a mouse click, so you won't need any skills or previous experience to be able to take advantage of it. Since you will be able to work with different releases of PHP concurrently, you could customize the software environment for each website which you host in the account if required. A php.ini file with a few lines in it placed in a domain folder will permit you to set what version of PHP this site will use and if APC should be on or off for it. These settings will have priority over those for the account as a whole, so you could run various scripts and take advantage of different web accelerators for Internet sites that are in the same account.
