PHP SOAP复杂数组处理

Question

似乎PHP无法正确处理复杂数组。使用PHP 5.

WSDL

PHP

$options['classmap'] = array('WsdService_QueryCostParams'=>'WsdService_QueryCostParams', 'WsdService_CostHotel'=>'WsdService_CostHotel');
$server = new SoapServer($url . "?" . $classname.'.wsdl', $options);
$server->setClass($classname);
$server->handle();

SoapClient的输出转储

stdClass::__set_state(array(
    'WsdService_CostHotel' => 
    array (
    0 => 
    WsdService_CostHotel::__set_state(array(
       'id' => 'HKG001',
       'day_cell_array' => 
      array (
      ),
       'reserv_policy' => NULL,
       'cancel_policy' => NULL,
       'category_array' => 
      stdClass::__set_state(array(
      )),
       'btype_value' => NULL,
    )),
    1 => 
    WsdService_CostHotel::__set_state(array(
       'id' => 'HKG002',
       'day_cell_array' => 
      array (
      ),
       'reserv_policy' => NULL,
       'cancel_policy' => NULL,
       'category_array' => 
      stdClass::__set_state(array(
         'WsdService_CostHotelCategory' => 
        stdClass::__set_state(array(
           'value' => 'STANDARD',
           'name' => 'Standard',
        )),
      )),
       'btype_value' => NULL,
    )),
  ),
))

我期望的是一个没有围绕实际数据的额外数组的数组。
