This new screencast from NETTUTS.com introduces you to the CodeIgniter framework and helps you build a small sample application to see where all the pieces fit.

In this week's 30 minute screencast, I'm going to show you how easy it is to work with the MVC pattern and CodeIgniter. This video is aimed at beginners who have no experience with a PHP framework. For demonstration purposes, we'll be building a simple image upload utility. We'll then perform some validation, save the file to our uploads folder, and automatically create a respective thumbnail.

You can check out the screencast in-page or just download the source and get started.
