I need to adopt a PHP MVC framework. I've done a bunch of PHP MVC work myself. Now I want to break away from reinventing everything and take advantage of a framework. This, of course, is for more than just MVC. Frameworks can offer solutions to such things as user authentication, forms, etc. that might be of value.

In addition to this, I need to get a mid-complexity MVP done in about ten to fifteen days for a presentation. I'm a quick study and already have chunks of the project coded, so part of it will be refactoring.

I've been looking at ZF2 primarily but Yii keeps coming-up here and there. Interested to learn what HN might have to say about these and the other choices out there.

Context without letting the cat out of the bag: A site where members place orders (and pay) for services and service providers sign-up to offer these services. Free and paid memberships. Ratings system for both service buyers and providers. Lightweight chat and maybe forum/s. English only at first but i18n will probably be a must later-on.
