PHP is one of the most used server-side programming languages. Many popular content management system and frameworks such as WordPress, Magento, and Laravel are written in PHP. At the time of writing, the default Ubuntu 20.04 repositories include PHP 7.4 version. Before installing getting started, you should already have install Ubuntu on your instance and have install Apache2.4 running as your web server.
Install and Configure PHP 7.4
Update all available repositories on your system and install the Apache webserver using the apt command below.
sudo apt update && sudo apt upgrade -y
In this step we will install and configure PHP 7.4. By default, the official Ubuntu 20.04 repository provides PHP 7.4 packages.

ENTER to confirm, and the installation will proceed.

sudo nano /etc/apache2/mods-enabled/dir.conf
