Symfony (https://symfony.com/ https://symfony.com/) and Slim (http://www.slimframework.com/ http://www.slimframework.com/) are also worth looking at. Though since Symfony has become more modularized, I think it can also be used as a micro framework. I've also started looking at Flask and Django of Python, can't help the feeling, that the Python frameworks are a bit more mature in terms of breaking changes.
