I have tried using the below code but i keep getting a null reply.
 $user = $collection->findOne(["_id"=> "5ebb4d14ac4ad9500c235a22"]);
    while( $user !==null )
    {
        $arr[]  = array(
            'template'=> $user['template'],
        );
        return ($arr);
    }
i did some research and i think it has something to do with the id being of type object.
