How to Enable and Use HHVM
Learn how to start using HHVM on your SiteGround Cloud Hosting
In this tutorial we will show you how to enable and use HHVM for your website. Note, that at this point HHVM is available only on our customers, hosted on Dedicated servers with the Booster pack and the new Cloud hosting platform based on Linux containers.
To enable HHVM, you need to login to your cPanel and open the SuperCacher tool, located in the Advanced tab.
Once you do that, go to the HHVM tab.
Next, simply click on the ON/OFF toggle to enable HHVM for this hosting account.
Finally, you need to add the following to your .htaccess files in order to enable HHVM for those folders you want:
AddHandler fastcgi-script .php
That's it, all the scripts in that folder and the folders in it will use HHVM to compile php files.
