/**
|
|
* AnnotationClassLoader loads routing information from a PHP class and its methods.
|
|
*
|
|
* You need to define an implementation for the configureRoute() method. Most of the
|
|
* time, this method should define some PHP callable to be called for the route
|
|
* (a controller in MVC speak).
|
|
*
|
|
* The @Route annotation can be set on the class (for global parameters),
|
|
* and on each method.
|
|
*
|
|
* The @Route annotation main value is the route path. The annotation also
|
|
* recognizes several parameters: requirements, options, defaults, schemes,
|
|
* methods, host, and name. The name parameter is mandatory.
|
|
* Here is an example of how you should be able to use it:
|
|
* /**
|
|
* * @Route("/Blog")
|
|
* * /
|
|
* class Blog
|
|
* {
|
|
* /**
|
|
* * @Route("/", name="blog_index")
|
|
* * /
|
|
* public function index()
|
|
* {
|
|
* }
|
|
* /**
|
|
* * @Route("/{id}", name="blog_post", requirements = {"id" = "\d+"})
|
|
* * /
|
|
* public function show()
|
|
* {
|
|
* }
|
|
* }
|
|
*
|
|
* On PHP 8, the annotation class can be used as an attribute as well:
|
|
* #[Route('/Blog')]
|
|
* class Blog
|
|
* {
|
|
* #[Route('/', name: 'blog_index')]
|
|
* public function index()
|
|
* {
|
|
* }
|
|
* #[Route('/{id}', name: 'blog_post', requirements: ["id" => '\d+'])]
|
|
* public function show()
|
|
* {
|
|
* }
|
|
* }
