How To Install PHP 7.3 on Ubuntu 20.04

In this article, we want to teach you How To Install PHP 7.3 on Ubuntu 20.04.

PHP is an open-source server-side scripting language that many devs use for web development.

It is also a general-purpose language that you can use to make lots of projects, including Graphical User Interfaces (GUIs).

The abbreviation PHP initially stood for Personal Homepage. But now it is a recursive acronym for Hypertext Preprocessor.

PHP is mostly used for making web servers. It runs on the browser and is also capable of running on the command line. So, if you don’t feel like showing your code output in the browser, you can show it in the terminal.
