# CodeIgniter 4 Framework
|
||
|
|
|
||
|
|
## What is CodeIgniter?
|
||
|
|
|
||
|
|
CodeIgniter is a PHP full-stack web framework that is light, fast, flexible and secure.
|
||
|
|
More information can be found at the [official site](https://codeigniter.com).
|
||
|
|
|
||
|
|
This repository holds the distributable version of the framework.
|
||
|
|
It has been built from the
|
||
|
|
[development repository](https://github.com/codeigniter4/CodeIgniter4).
|
||
|
|
|
||
|
|
More information about the plans for version 4 can be found in [CodeIgniter 4](https://forum.codeigniter.com/forumdisplay.php?fid=28) on the forums.
|
||
|
|
|
||
|
|
The user guide corresponding to the latest version of the framework can be found
|
||
|
|
[here](https://codeigniter4.github.io/userguide/).
|
||
|
|
|
||
|
|
## Important Change with index.php
|
||
|
|
|
||
|
|
`index.php` is no longer in the root of the project! It has been moved inside the *public* folder,
|
||
|
|
for better security and separation of components.
|
||
|
|
|
||
|
|
This means that you should configure your web server to "point" to your project's *public* folder, and
|
||
|
|
not to the project root. A better practice would be to configure a virtual host to point there. A poor practice would be to point your web server to the project root and expect to enter *public/...*, as the rest of your logic and the
|
||
|
|
framework are exposed.
|
||
|
|
|
||
|
|
**Please** read the user guide for a better explanation of how CI4 works!
