This article is the third in a mini-series of quick reference guides for installing Apache, PHP, and MySQL in Ubuntu 16. In this article we will cover the installation of PHP 7 and the Apache PHP module. Lastly we’ll verify PHP works with Apache.
My environment for these steps is Ubuntu 16 running on VirtualBox in Windows 10 x64.
Check out the previous article where we installed Apache HTTP Server.
Let’s install PHP now, along with the Apache PHP module
Open a new terminal and type
sudo apt-get install php libapache2-mod-php
When it has finished you can verify the PHP version that was installed by using the
