Tutorial Install and Configure PHP on Ubuntu 22.04

Websites are expanding every day and reaching a larger audience. So far, more than 125000000 domains have been registered on the Internet, which indicates the rapid expansion of the Internet. As the website audience grew, HTML no longer met the needs of webmasters and needed a programming language to act like Desktop software and be easily scalable. Languages such as PHP, Asp, Java and etc were created to serve websites. In this article, we are going to teach you how to install and configure PHP on Ubuntu 22.04.

What is PHP?

PHP is the most popular programming language for designing dynamic websites and is a free and open-source language. This scripting language can be integrated with HTML and its syntax is similar to C and Perl language. PHP is a server-side language, meaning that PHP code is interpreted on the server and generates HTML output or another output that is visible to the user. PHP was written in the C programming language by Rasmus Lerdorf in 1994 for use in monitoring online resumes and related personal information.
