running this, following error:

catchable fatal error: object of class mybundle\entity\userapartment not converted string 500 internal server error - contexterrorexception

how can error fixed?
in advance!

you trying echo object

echo ($userapt->key() . ' => ' . $userapt->current()) . "\n";

you can solve implementing public function __tostring() {} method in userapartament class. in way when try echo $user->current() use __tostring() method show string value of object.
