CodeIgniter is a PHP web application framework that uses the model-view-controller (MVC) architectural pattern. MVC separates an application into three main logical components: the model, the view, and the controller. CodeIgniter provides further documentation and resources on its website for learning more about using the framework and MVC design pattern.
