The CodeIgniter framework v4

CodeIgniter 4 Development

, _(*1)

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., _(*2)

This repository holds the source code for CodeIgniter 4 only. Version 4 is a complete rewrite to bring the quality and the code into a more modern version, while still keeping as many of the things intact that has made people love the framework over the years., _(*3)

More information about the plans for version 4 can be found in CodeIgniter 4 on the forums., _(*4)

Documentation

The User Guide is the primary documentation for CodeIgniter 4., _(*5)

You will also find the current in-progress User Guide. As with the rest of the framework, it is a work in progress, and will see changes over time to structure, explanations, etc., _(*6)

You might also be interested in the API documentation for the framework components., _(*7)

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., _(*8)

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., _(*9)

Please read the user guide for a better explanation of how CI4 works!, _(*10)

Repository Management

CodeIgniter is developed completely on a volunteer basis. As such, please give up to 7 days for your issues to be reviewed. If you haven't heard from one of the team in that time period, feel free to leave a comment on the issue so that it gets brought back to our attention., _(*11)

[!IMPORTANT] We use GitHub issues to track BUGS and to track approved DEVELOPMENT work packages. We use our forum to provide SUPPORT and to discuss FEATURE REQUESTS., _(*12)

If you raise an issue here that pertains to support or a feature request, it will be closed! If you are not sure if you have found a bug, raise a thread on the forum first - someone else may have encountered the same thing., _(*13)

Before raising a new GitHub issue, please check that your bug hasn't already been reported or fixed., _(*14)

We use pull requests (PRs) for CONTRIBUTIONS to the repository. We are looking for contributions that address one of the reported bugs or approved work packages., _(*15)

Do not use a PR as a form of feature request. Unsolicited contributions will only be considered if they fit nicely into the framework roadmap. Remember that some components that were part of CodeIgniter 3 are being moved to optional packages, with their own repository., _(*16)

Contributing

We are accepting contributions from the community! It doesn't matter whether you can code, write documentation, or help find bugs, all contributions are welcome., _(*17)

Please read the Contributing to CodeIgniter., _(*18)

CodeIgniter has had thousands on contributions from people since its creation. This project would not be what it is without them., _(*19)
