CodeIgniter is an Application Development Framework - a toolkit - for people who build web sites using PHP. Its goal is to enable you to develop projects much faster than you could if you were writing code from scratch, by providing a rich set of libraries for commonly needed tasks, as well as a simple interface and logical structure to access these libraries. CodeIgniter lets you creatively focus on your project by minimizing the amount of code needed for a given task.
This repo contains in-development code for future releases. To download the latest stable release please visit the CodeIgniter Downloads page.
You can find a list of all changes for each release in the user guide change log.
This is a fork of CodeIgniter 3, with the goal of keeping it up to date with PHP 8.4 and beyond. There is no intention to add new features or change the way CI3 works. This is purely a maintenance fork.
The original CodeIgniter 3.x branch is no longer maintained, and has not been updated to work with PHP 8.2, or any newer version. This fork is intended to fill that gap.
If the original CodeIgniter 3.x branch is updated to work with PHP 8.2+, and starts to be maintained again, this fork might be retired.

PHP version 5.6 or newer is recommended.
It should work on 5.3.7 as well, but we strongly advise you NOT to run such old versions of PHP, because of potential security and performance issues, as well as missing features.
