                    $gateway_array []= array(
                        "id"=>$value['id'],
                        "name" => $value['username']
                    );
                }                   
            } 
        }
           
    }

когда происходит ajax вызов, он переходит в функцию, а затем показывает выбранное раскрывающееся значение
