Symfony is a PHP framework as well as a set of reusable PHP components and libraries. It uses the Model-View-Controller design pattern. This framework has become very popular, mainly due to the vast number of reusable PHP components. These components are not limited to the framework itself but can be found throughout the PHP community, such as Drupal, WordPress, phpBB, and Laravel.
Symfony web framework is based on Model-View-Controller (MVC) architecture. The model represents the structure of our business entities. View shows the models to the user in the best possible way depending on the situation. The controller handles all the request from the user, does the actual work by interacting with Model and finally provides the View with the necessary data to show it to the user.
