Symfony

Architecture

Routes

Controller

Minimal, just a link between Route and Service: receives a request, calls a service, generates a response. Handles forms, views, redirects...
Usually inherits AbstractController

Service

Class that encapsulates a business logic.
Is instanciated within a global Container (service is registred).
