PHP soapCall - 不传递所有参数

Question

这是我的脚本的开头：

  <?php
  $soapUrl = 'http://webservicetocall.com/Interface/ChannelConnect.asmx?WSDL';

  $client = new SoapClient($soapUrl);

  $headerBody = array(
    'From' => array(
      'Credential' => array(
        'userName' =>  'MYUSERNAME',
        'password' => 'MYPASSWORD',
      )
    ),
  );

  $params = array(
    'OTA_HotelAvailRQ' => array(
      'BestOnly' => 'false',
      'SummaryOnly' => 'false',
      'HotelStayOnly' => 'true',
      'MaxResponses' => 0,
      'ExactMatchOnly' => 'true',
      'POS' => array(
        'Source' => array(
          'Requestor' => array(
            'ID_Context' => 'Synxis',
            'ID' => '10',
            'CompanyName' => array(
              'Code' => 'AAAA',
            ),
          ),
        ),
      ),
      'AvailableRequestSegements' => array(
        'AvailableRequestSegment' => array(
          'AvailReqType' => 'Room',
          'StayDateRange' => array(
            'Start' => '05/10/2015',
            'End' => '05/17/2015',
          ),
          'RoomStayCandidate' => array(
            'Quantity' => '1',
            'GuestCounts' => array(
              'GuestCount' => array(
                'AgeQualifyingCode' => '10',
                'Count' => '1',
              ),
            ),
          ),
          'HotelSearchCriteria' => array(
            'Criterion' => array(
              'HotelRef' => array(
                'HotelCode' => '12345',
              ),
            ),
          ),
        ),
      ),
    ),
  );

  $ns = 'http://htng.org/1.1/Header/';

  $client = new SoapClient($soapUrl, array(
      'trace' => 1,
      'cache_wsdl' => WSDL_CACHE_NONE,
      'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
    )
  );

  $header = new SOAPHeader($ns, 'HTNGHeader', $headerBody);

  $client->__setSoapHeaders($header);

  $hotel_info = $client->__soapCall('CheckAvailability', $params);

  $last_call = $client->__getLastRequest();

以下是$ client-＆gt; __ getLastRequest（）返回的内容。

我不太明白为什么我的整个数组都没有作为正文的一部分传递。有任何想法吗？这是我第一次使用SoapClient类的经历，我无法找到有关如何正确使用它的任何好的解释。
