PHP frameworks are finally becoming sane. Instead of re-inventing the wheel ,they share popular components wether it is from doctrine , symfony , etc ... The PSR stuff and composer is a huge step in the right direction , we are getting there , at last.
another promise framework is Silex based on Symfony , it's easy to wire any symfony component through services and unlike Laravel it doesnt rely on Static methods or Singletons.
