CodeIgniter is a PHP full-stack web framework that is light, fast, flexible, and secure.More information can be found at theofficial site.

This repository holds the pre-alpha 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.

This is pre-release code and should not be used in production sites.

More information about the plans for version 4 can be found inthe announcement on the forums.

The current documentation can be foundhere. As with the rest of the framwork, it is currently a work in progress, and will see changes over time to structure, explanations, etc.

index.php is no longer in the root of the project! It has been moved inside thepublic folder,for better security and separation of components.

This means that you should configure your web server to "point" to your project'spublic folder, andnot 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 enterpublic/..., as the rest of your logic and theframework are exposed.

Please read the user guide for a better explanation of how CI4 works!The user guide updating and deployment is a bit awkward at the moment, but we are working on it!

We use Github issues to trackBUGS and to track approvedDEVELOPMENT work packages.We use ourforum to provide SUPPORT and to discussFEATURE REQUESTS.

If you raise an issue here that pertains to support or a feature request, it willbe 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.

Before raising a new Github issue, please check that your bug hasn't alreadybeen reported or fixed.

We use pull requests (PRs) for CONTRIBUTIONS to the repository.We are looking for contributions that address one of the reported bugs orapproved work packages.

Do not use a PR as a form of feature request.Unsolicited contributions will only be considered if they fit nicelyinto the framework roadmap.Remember that some components that were part of CodeIgniter 3 are being movedto optional packages, with their own repository.

Weare accepting contributions from the community, specifically those identified as part of phase 2.

We will try to manage the process somewhat, by adding a "Help wanted" label to those that we arespecifically interested in at any point in time. Join the discussion for those issues, and let us knowif you want to take the lead for one of them.

We are not looking for out-of-scope contributions, only those that would be considered part of our controlled evolution!
