In the most recent post to his site Brandon Savage suggests that choosing and using a framework for you application isn't even needed.

Looking through the list of PHP frameworks can be daunting. Zend Framework. Laravel. Cake. Symfony. Picking one and learning it can seem like the most important design decision you'll make. And yet, picking a framework is actually one of the least important decisions you face. In fact, you don't need a framework at all.

He starts with a brief history of (PHP) frameworks and talks about their evolution from a set of common libraries out to the full stack versions we have today. He moves on to the "PSR and Composer era" where the lines started to blur a bit. With the renewed emphasis on packages in an easy to install method, frameworks started to become less important.

Now, instead of having a bunch of siloed frameworks that can't work together, there are (supposedly) standards for how they can integrate. An added bonus is that library creators can follow the same standards, making their libraries compatible with all the frameworks that implement the PSR standards.
