Which frameworks are popular in PHP?

The answer

Laravel and Symfony are the frameworks most often discussed, and CodeIgniter, CakePHP, Yii and Slim are also used. They differ in emphasis: some are full-featured, some are lightweight, and Slim is aimed at small services and APIs. The best choice depends on your project, your team and the available documentation. As a learner, pick one framework, follow its official documentation and learn its concepts well, because the ideas transfer to the others.
