CodeIgniter 4 Application Starter
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.
This repository holds a composer-installable app starter. It has been built from the development repository.
More information about the plans for version 4 can be found in the announcement on the forums.
The user guide corresponding to this version of the framework can be found here.
Installation & updates
composer create-project codeigniter4/appstarter then
composer update whenever
there is a new release of the framework.
When updating, check the release notes to see if there are any changes you might need to apply
app folder. The affected files can be copied or merged from
.env and tailor for your app, specifically the baseURL
and any database settings.
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!
