How Does PHP Framework Operate?

MVC is a model-view-controller (MVC) framework. When a user requests a resource, the controller is the first to respond. The controller then understands the request and, if necessary, accesses the real databases.

Assume you're looking for a customer with id 6; the controller will accept your request and then ask the models to find the record with id 6. The record will be returned to the controller by the CodeIgniter models.
