APC, which stands for Alternative PHP Cache, is a framework used for caching the compiled source code of a given script application, which could speed up a database-driven site several times. When a PHP page is accessed, the script pulls the website content which should be displayed from a database, parses and compiles the code, and then the result is displayed to the visitor. While this is necessary for websites with routinely changing content, it's a waste of processing time and system resources for a website that doesn't change, for example an informational portal that displays the exact same content on a regular basis. As soon as the webpages for such a website are compiled, APC caches them and delivers them any time a visitor opens them. Since this saves the time to collect content from the database and to parse and compile the code, your website will load much quicker. APC is very effective especially for scripts with larger source code.
APC (PHP Opcode Cache) in Shared Hosting
APC is pre-installed on our outstanding cloud platform, therefore you can use it for your applications regardless of the shared hosting package that you select when you register. The module can be activated through the Hepsia hosting Control Panel which is used to control the shared accounts and just a few minutes later it will speed up your sites because it'll start caching their code. If you need to run sites with various system requirements or use specific web accelerators for some of them, you can customize the software environment by putting a php.ini file inside the preferred domain folder. In this way, you could enable or disable APC not just for a specific site without affecting the other websites in the account, but also for a specific version of PHP since our platform supports multiple versions simultaneously.
APC (PHP Opcode Cache) in Semi-dedicated Servers
APC is set up on the state-of-the-art cloud web hosting platform where all semi-dedicated server accounts are made, so you could employ it irrespective of the package you select. Enabling the module is performed through the Hepsia Control Panel and takes just a mouse click, so you will not need any skills or previous experience to be able to take full advantage of it. Since you will be able to employ several releases of PHP concurrently, you could customize the software environment for each site that you host in the account if needed. A php.ini file with several lines in it placed in a domain folder will permit you to set what release of PHP this particular site will use and whether APC should be on or off for it. These settings will have priority over those for the account in general, so you can run various scripts and use different web accelerators for websites that are in the same account.
