속성을 사용하여 PHP8 코드의 기능을 확장하는 방법은 무엇입니까?

#[Attribute]
class Route
{
    public function __construct(public string $path) {}
}

#[Route('/index')]
class HomeController
{
    #[Route('/hello')]
    public function sayHello(string $name)
    {
        echo "Hello, ".$name;
    }
}

#[Attribute(Attribute::TARGET_METHOD)]
class Authorized
{
    public function __construct(public string $permission) {}
}

class ApiController
{
    #[Authorized('admin')]
    public function saveData($data)
    {
        // 只有拥有'admin'权限的用户才能调用该方法
        // ...
    }
    
    #[Authorized('user')]
    public function getUserData()
    {
        // 只有拥有'user'权限的用户才能调用该方法
        // ...
    }
}

#[Attribute(Attribute::TARGET_METHOD)]
class Route
{
    public function __construct(public string $path) {}
}

class Router
{
    #[Route('/home')]
    public function home()
    {
        echo "Home Page";
    }
    
    #[Route('/about')]
    public function about()
    {
        echo "About Page";
    }
}

$router = new Router();
if (isset($_GET['path'])) {
    $path = $_GET['path'];
    $reflection = new ReflectionClass($router);
    foreach ($reflection->getMethods() as $method) {
        $routeAttribute = $method->getAttributes(Route::class);
        if (!empty($routeAttribute) && $routeAttribute[0]->newInstance()->path === $path) {
            $method->invoke($router);
        }
    }
}
