On the Web Species blog there's a new post from Juozas Kaziukenas about the new era of PHP frameworks that are coming out (or might be already here). This new group of frameworks is redefining the PHP framework world:

I have worked on a lot of different systems and projects in my years and most of that was spent doing PHP. However just recently I have noticed a new major point in time - a new era of PHP frameworks. Seems like everything is changing these days. I want to discuss what I think the current state is, what’s wrong with it and how the new gang of frameworks is going to change it.

Juozas starts with a brief history of the "why" and "how" PHP frameworks came to be and how they've improved over time. In this new generation things like dependency injection containers and annotations are changes for the better. Three frameworks mentioned specifically as driving forces in this new movement are Zend Framework 2.0, Lithium and Symfony2.
