depends on your need sir.
Let's say,you'd like to build RESTFul APIs only, you can go for Slim framework. It has good OAuth support.
Ground-up application development, you can go for Laravel, Magento CogeIgniter, or CakePHP. But there's more.
There's also Zend and Symfony.
There's no "best" framework, it all depends on how you'll use them and how they match your style, SDLC, architecture, etc.Each of them has their own pros and cons; and different learning curves.
