Route.php

TLDR

The Route.php file is a part of the Illuminate\Routing namespace and contains the Route class. This class represents a route in the application. It handles various functionalities related to route handling such as matching requests, running the route action, parsing route parameters, compiling the route, and more.

Methods

__construct($methods, $uri, $action)

The constructor method of the Route class. It initializes the properties of the route instance.

parseAction($action)

This method parses the route action into a standard array.

run()

This method runs the route action and returns the response.

isControllerAction()

Checks whether the route's action is a controller.

Determines if the route action is a serialized Closure.

runController()

Runs the route action if it is a controller.

getController()

Gets the controller instance for the route.

getControllerClass()

Gets the controller class used for the route.
