CodeIgniter - MVC Framework

CodeIgniter is based on the Model-View-Controller (MVC) development pattern . MVC is a programming approach that separates application logic from presentation. In practice, this allows your web pages to contain minimal scripting, since the presentation is separated from PHP scripts.

• The modelrepresents your data structures. Typically, your model classes will contain functions to help you retrieve, insert, and update information in your database.
• The viewis the information that is presented to the user. A view is usually a web page, but in CodeIgniter a view can also be a page fragment such as a header or footer. It could also be an RSS page, or any other type of "page".
• The controllerserves as an intermediary between the model, the view, and any other resources needed to process an HTTP request and create a web page.
