Using a Closure inside a class to return a static function value

I am just starting with Anonymous functions namely Closures and I've run into an issue. I am using the Closure to call a static function inside a class called Project to return a value in another class called Application. Below is a simplified version of my problem

    class Project{

         public function __construct(){

             self::ProcessParams(function() {

                        return Application::return_param('1');

                    }, 'param2', 'param3');

              }
         }

         public static function ProcessParams($param1, $param2, $param3){

           var_dump($param1);

         }

    }

My problem is the var_dump() in the ProcessParams function doesn't return the requested value but rather inserts the whole Project class into $param1

object(Closure)#90 (1) { ["this"]=> object(Project)#34 (3) { ..... }

What am I doing wrong??

Thanks

You need to call the closure in order to retrieve it's return value:

var_dump($param1());
