Most of my small personal projects tend to get built with CodeIgniter (CI), which is a simple to use, fast, lightweight PHP5 MVC framework.
For a while now I’ve had an itch to build something fun against the Facebook API so I can start learning how Open Graph works, and as a primer to building a “proper” Facebook integrated application. I also realised I hadn’t actually tried using CodeIgniter 2.x since it was released (quite some time ago). With an abundance of free time this weekend it seemed like the perfect time to get hacking!
Before I could build anything I would need to know one thing: just how do you connect a CodeIgniter app to Facebook?
