SOAP API call with PHP

Question

Working on this for a week now. Having trouble executing this code. I want to retrieve data via SOAP and work with it in PHP. My trouble is, that I am having trouble sending the 'RequesterCredentials'.

I will show the xml code so you all can see the info I am trying to send, and then the PHP code I am using.

XML SAMPLE CODE

POST /AuctionService.asmx HTTP/1.1
Host: apiv2.gunbroker.com
Content-Type: text/xml; charset=utf-8
Content-Length: 200
SOAPAction: "GunBrokerAPI_V2/GetItem"

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
 <soap:Header>
   <RequesterCredentials xmlns="GunBrokerAPI_V2">
     <DevKey>devkey</DevKey>
     <AppKey>appkey</AppKey>
   </RequesterCredentials>
 </soap:Header>
 <soap:Body>
<GetItem xmlns="GunBrokerAPI_V2">
  <GetItemRequest>
    <ItemID>312007942</ItemID>
    <ItemDetail>Std</ItemDetail>
  </GetItemRequest>
</GetItem>

PHP CODE THAT I AM USING TO MAKE THE CALL

$client = new SoapClient("http://apiv2.gunbroker.com/AuctionService.asmx?WSDL");

$appkey = 'XXXXXX-XXXXXX-XXXXXX';
$devkey = 'XXXXXX-XXXXXX-XXXXXX';

$header = new SoapHeader('GunBrokerAPI_V2','RequesterCredentials',array('DevKey' => $devkey,'AppKey' => $appkey),0);
$client->__setSoapHeaders(array($header));

$result = $client->GetItem('312343077');

echo '<pre>',print_r($result,true),'</pre>';

THE RESULT I GET

stdClass Object
(
[GetItemResult] => stdClass Object
    (
        [Timestamp] => 2012-11-07T18:17:31.9032903-05:00
        [Ack] => Failure
        [Errors] => stdClass Object
            (
                [ShortMessage] => GunBrokerAPI_V2 Error Message : [GetItem]
You must fill in the 'RequesterCredentialsValue' SOAP header for this Web Service method.
                [ErrorCode] => 1
            )
// the rest if just an array of empty fields that I could retrieve if i wasnt havng problems.

Im not sure if the problem is the way Im sending the SoapHeaders or if I am misunderstanding the syntax. I would greatly appreciate any and all help.

Answer 1

Use object instead of associative array for headers:

$obj = new stdClass();

$obj->AppKey = $appkey;
$obj->DevKey = $devkey;

$header = new SoapHeader('GunBrokerAPI_V2','RequesterCredentials',$obj,0);

And next problem you might face will be at GetItem call, you allso need object, wrapped in associative array:

$item = new stdClass;
$item->ItemID = '312343077';
$item->ItemDetail = 'Std';

$result = $client->GetItem(array('GetItemRequest' => $item));
