Best PHP framework for jQuery?
I've read all the answers on stackoverflow for similar questions but no one really laid down an explanation: **why** is zend/symfony/kohana/cakePHP the best for jQuery? what is the difference?

I'm writing a snazzy ultra-cool web 2.0 app with google maps and facebook connect integration plus a bunch of other APIs. Almost everything will be AJAX vis JSON. For me PHP is a burden, an unnecessary evil. I need database control, almost always via JSON. I need user authentication. This is all. Nothing fancy. And I need it to scale. Most of all I need it to work effortlessly with jQuery, I need it to be jQuery's BFF, and I need to know why it is so.

Thank you very much
