In plain English

CodeIgniter is an open-source PHP web framework originally developed by EllisLab. PHP is a programming language used for building websites and web applications that run on a server. A framework like CodeIgniter provides a structured starting point and a collection of reusable tools, for routing incoming requests, talking to databases, managing sessions, and more, so developers don't have to write all of that infrastructure from scratch. It supports PHP 7 and PHP 8.
