In no particular order, here is a list of PHP frameworks that I am considering:
ez Components purports to be an "Enterprise" PHP library. This is very appealing to me, in that I am not interested in making a blog in 20 minutes. My typical applications need to integrate with back-end corporate systems, have non-trivial security and filtering rules, and the like. The framework at first glance is much larger than some competitors listed here, so likely carries with it a larger learning curve. As much as I enjoy the intellectual excercise of framework development, I'd much rather have the productivity and consistency across my programming team that a framework brings. More on this after I build my first experiment with ezComponents.
