However, the good news is that in the new versions of cPanel, we can change the PHP version from 5.3 to 5.6 and customize the module we want to use, including enabling APC, Memcached, cURL, Ioncube modules. Loader, ... In this article, I will introduce you through the PHP version and customize the cache system if you want to experience the system. But you should also note that not all hosts that are using cPanel can also be turned on, depending on whether or not your provider has enabled this feature or is using the latest version of cPanel. cPanel or not, so if you do not see it, do not be surprised. I have tested on some packages and found that there are currently StableHost and 247-Host (I have been using 6 months, wait a few months to review) is the best operation, while A2Hosting and InmotionHosting also do not have this feature. . How to enable APC and Memcached modules on cPanel First you need to log into cPanel, of course, then drag down to the Software / Service section and navigate to the Select PHP Version.
