In this tutorial, we will show you how to install PHP 5.6 on Ubuntu 16.04 LTS. For those of you who didn’t know, PHP (recursive acronym for PHP: Hypertext Preprocessor) is an open-source, popular general-purpose scripting language that is widely-used and best suited for developing websites and web-based applications. It is a server-side scripting language that can be embedded in HTML. By default, Ubuntu 16.04 (Xenial) now comes with PHP 7.0. You can install PHP 5.6 in parallel and switch between them using the following instructions.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS.
