Building a Simple Blogger with the Code Igniter PHP Framework

In case you haven't heard about it, Code Igniter is a powerful, comprehensive framework written in PHP 4 that provides developers with a robust set of classes and helpers that can be used for building different web applications by means of the Model-View-Controller pattern, which separates application logic from visual presentation.

Thus, in this series of articles I'm going to explain how to build a basic blogger with Code Igniter. I will explain it in a step-by-step fashion to allow you to get an excellent grounding in its main features, as well as learn how to implement the MVC approach in a real-world situation.

This is a sample blog with Code Igniter you can download it here.
