I have been recently introduced to the Kohana PHP Framework. I can say, after just a bit of research and few hours of using the framework, that I can already realize the benefits of using such a package.

Kohana is a fork of the CodeIgniter PHP Framework. I do not have any experience with the CodeIgniter Framework, so unfortunately I cannot provide an efficient compare/contrast between the two.

As my development with the framework progresses, I will definitely post more information.
