Could anyone tell me how does Symfony framework use comment out the area to do something? I'm a quite junior developer, before using Symfony, I have never seen any syntax like this.
/**
* @var integer
*
* @ORM\Column(name="id", type="integer", options={"unsigned":true})
* @ORM\Id
* @ORM\GeneratedValue(strategy="IDENTITY")
*/
or
/**
*
* @Route("/products/add_favorite/{id}", name="product_add_favorite", requirements={"id" = "\d+"})
*/
I know /*......*/ is an area to comment out and used to define a function before it. But why it comes functionality here, Hope you can tell me where do I miss.
In Symfony you have the option to use annotation, xml or yml configuration.' By default the annotation is used, that's what you see in this case. Personally I think it's a nice way to get your configuration close to the actual code which it affects to.
