Laravel (http://laravel.com/) if you want to pick up best practices (yes, there are best practices in PHP) and mess around with MVC and such, or Slim Framework (http://www.slimframework.com/) if you want little more than the bare essentials. In both cases, I would recommend using Twig for templates. None of this is particularly controversial, though, but in my opinion the only faster way to get a site up is wordpress, but on the programming side, that's a lot messier to work with.
Of course, the people who will recommend Ruby and Python and whatnot are right too - you can get a reasonable set of frameworks and deployment strategies in various languages. But the case for PHP is, essentially, lack of overhead and low cost deployment. If you can stand an ugly looking weakly typed ad-hoc language, that is.
