In a new post to his blog today, Daniel Krook looks (very) briefly at two of the popular PHP framework offerings - CakePHP and CodeIgniter.
In short, it's getting easier to leave most of the drudgery of building PHP applications to the framework, and spend more time developing the logic behind my applications.
He touches on what they are and how they work as well as his opinions on their strengths (CakePHP is more full-featured, but CodeIgniter's learning curve is easier).
