Install PHP on Ubuntu 20.04

You have Apache installed to serve your content and MySQL installed to store and manage your data.

You’ll also need libapache2-mod-php to enable Apache to handle PHP files. Core PHP packages will automatically be installed as dependencies.

To install these packages, please the following command:

apt install php libapache2-mod-php php-mysql

remember: With the above command, Ubuntu installed the latest version of PHP, so if you need any version on PHP, you should type version of PHP.

 

Testing PHP Processing on your web server

Now that you have a custom location to host your website’s files and folders, we’ll create a PHP test script to confirm that Apache is able to handle and process requests for PHP files.

Create a new file named info.php inside your custom webroot folder:

nano /var/www/html/info.php

add below PHP command on it and save the file

<?php
phpinfo();

To test this, go to your web browser and access your server’s domain name or IP address, followed by the script name, which in this case is info.php:
