How to install PHP MySQL on Ubuntu 16.04

I believe since ubuntu 16.04 LTS, the default php version on ubuntu repo is php version 7.0, so if you want php on ubuntu 16.04, you have to use php 7.0.

Installing php 7 is little bit different, i mean the package name is different, but everything else is still the same, all right let's get started.

Before installing php 7, of course you need to have a web server, so first you need to install apache web server, on ubuntu 16.04 the installation of apache web server is like this:

sudo apt-get install apache2

sudo apt-get install libapache2-mod-php
