First, Rails is a framework. PHP is a language. PHP does not have built-in scaffolding support, just as Ruby--the language Rails is build on--does not. A framework like CakePHP, however, does support scaffolding.
Second, I see that you raised an objection to CakePHP because "you still have to do a bunch of stuff." That's true--with any framework, you're going to have to learn new conventions, configurations etc.
