I’ve published one before on the VestaCP Forums regarding how to install PHP 7.0 on Centos 7 with VestaCP. This tutorial is now for PHP 7.2 which has increased performance over PHP 7.0 and 7.1. If you have a handful of WordPress websites on PHP 5, you should upgrade. If you’re on PHP 7.0 from my previous tutorials, or are using my Server Installer Script then this will also work for you. I would advise upgrading when you have time.
