I think that it's more important for modern PHP programming to be familiar with PSR-0, Composer and the Model-View-Controller pattern than necessarily a specific framework, because depending on how simple this site needs to be it can be done entirely by pulling in, say, Twig and a url router and some other packages into Composer.<p>If you want a framework that does less for you, then consider Slim Framework. If you want one intended for scalable projects with a lot of existing libraries and helpers, then consider Laravel (though in the latter case, the learning curve can be a bit steep.)
