php - PHPのsoapclientのnull値を修正する方法

Question

soap-ui を使用すればデータを取得できますが、php soapclient を使用する必要があり、データを取得できません。

soap-ui の出力

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://webservice.bc/Interaction">
   <SOAP-ENV:Body>
      <ns1:QueryInteractionResponse>
         <productWarningArray>
            <ProductWarning>
               <Product>
                  <id>10008</id>
               </Product>
               <Color>
                  <id>4</id>
               </Color>
               <Value>Besinler, asetilsalisilik asitin emilimini yavaşlatır. Hızlı analjezi gerekliyse besinlerle birlikte verilmemelidir. Uzun süreli asetilsalisilik asit kullanımında, besinler, mide mukozasını korumaya yardımcı olur.</Value>

               </Product>
               <Color>
                  <id>4</id>
               </Color>
               <Value>Besinler, psödoefedrinin emilimini yavaşlatır.</Value>

<Value>Besinler, asetilsalisilik asitin emilimini yavaşlatır. Hızlı analjezi gerekliyse besinlerle birlikte verilmemelidir. Uzun süreli asetilsalisilik asit kullanımında, besinler, mide mukozasını korumaya yardımcı olur.</Value>

しかし、php soapclientを使用すると

$client = new SoapClient("http://webservice.bc/web.wsdl", array(
                        'exceptions'=>true,
                        'cache_wsdl'=>WSDL_CACHE_NONE,
                        'compression' => SOAP_COMPRESSION_ACCEPT | SOAP_COMPRESSION_GZIP | 5,
                        'features' => SOAP_SINGLE_ELEMENT_ARRAYS,
                        'encoding'=>' utf-8'
                    //  'features' => SOAP_SINGLE_ELEMENT_ARRAYS

                ));
                $result = $client->QueryInteraction($requestData);
                echo "<pre>";
                print_r($result);

値が得られませんでした...

                        )

                )

        )

)

そのヌル...

[Value] => stdClass Object
                            (
                            )

どうすれば問題を解決できますか?
