Thanks for the question about PHP7 on our servers. Currently, if you're on any server loaded with the default cPanel installation, then PHP 7 is not installed. Our hosting servers use the latest stable versions of centOS that includes the versions of PHP. Version 7 is not currently part of that build. However, if you are on a VPS or Dedicated server and you have root access, then you can install it yourself. If you do not have root access, you can request that it be installed for a VPS or dedicated server by submitting a verified support ticket. Our systems people can install it, but please understand that cPanel (the interface you use to work with the server outside of SSH) has only released support for that version in beta as per a post on their support community 1 day ago.
I hope that helps to answer your question! If you require further assistance, please let us know!
I just wanted to update this answer to let you know that PHP7 is available on our servers. You can change the version of PHP using the version switcher in the cPanel. The current available version of PHP in cPanel are: 5.2.17, 5.3.29, 5.4.45, 5.5.36, 5.6.22, and 7.0.7.
This information was provided to let you know that the servers have been updated. If you have any further questions or comments, please let us know.
