How can interfaces be utilized in PHP routing classes to ensure consistency and standardization in handling routes and requests?

To ensure consistency and standardization in handling routes and requests in PHP routing classes, interfaces can be utilized to define a contract that all routing classes must adhere to. By implementing interfaces, you can enforce a specific set of methods that must be present in each routing class, ensuring a consistent structure and behavior across the application.

// Define an interface for routing classes
interface RouterInterface {
    public function addRoute($method, $path, $callback);
    public function dispatch();
}

// Implement the interface in a routing class
class Router implements RouterInterface {
    public function addRoute($method, $path, $callback) {
        // Add route implementation
    }

    public function dispatch() {
        // Dispatch route implementation
    }
}
