Get route placeholder in a container

1

Not sure if this is possible or not but I’d like to get the value of a route placeholder in a container. Can this be done?

Example:

$c = $app->getContainer();

$c['Controller'] = function() {
	$userId = $params['userId'];  // how do I get the route placeholder value here?
	return new Controller($userId);
};

$app->get('/user/{userId}','Controller:getUserId');

class Controller {
	public function __construct($userId) {
		$this->userId = $userId;
	}

    public function getUserId($request,$response) {
        return $response->withJson($this->userId);
    }
}

I did get an answer on Stack Overflow and while it does work, it is a bit hacky as mentioned by the user who answered the question. Probably something that a container doesn’t need to deal with in the first place.

$c['Controller'] = function($c) {
    $routeInfo = $c['router']->dispatch($c['request']);
    $args = $routeInfo[2];
    $userId = $args['userId'];
    return new Controller($userId);
};

If I were to use it:

$app = new Slim\App;
$global = new Slim\Container;

$global['routeParam'] = function() use ($app) {
	return function ($name) use ($app) {
		$c = $app->getContainer();
		$placeholders = $c['router']->dispatch($c['request']);
    	return $placeholders[2][$name];
	};
};

// route file

$c = $app->getContainer();
$c['Controller'] = function() use ($global) {
	$routeParam = $global->routeParam;
	return new Controller($routeParam('userId'));
};

$app->get('/user/{userId}','Controller:getUserId');
