PHP SoapClient with SuperPages API

So I'm completely new to SOAP and the whole idea behind it, but I am forced to figure it out in order to work with the SuperPages API. For now, I am just trying to wrap my head around it, and how to make calls to the API. The API documentation can be found here: http://advertising.superpages.com/spapiweb/v2. I am able to login via the headers, but I can't quite figure out where to go from there. Here is documentation for the function I'm attempting to run:

getReportList

The getReportList method retrieves a list of the reports that are currently stored.

Request:

Field Name             Field Type  Field Description    Field
externalTransactionId   string(6)   External Transaction identifier used for logging. Provided by user. Optional

Response

     </return>
  </ns2:getReportListResponse>

</soap:Envelope>

My code:

 $options = array('trace' => true);
 $sp = new SoapClient('http://services.superpages.com/spexternalservicesv3/services/reportingservice?wsdl', $options);
 $header = new SoapHeader('[companyId]', '[username]', '[password]');
 $sp->__setSoapHeaders($header);

 echo "<pre>";
 var_dump($sp->__getFunctions()); //check that I'm at least doing something right
 echo "</pre>";

 $sp->__soapCall("getReportList",array("")); //empty array, because parameter is optional in documentation

My results:

array(5) {
  [0]=>
  string(59) "getReportURLResponse getReportURL(getReportURL $parameters)"
  [1]=>
  string(83) "scheduleAgencyReportResponse scheduleAgencyReport(scheduleAgencyReport $parameters)"
  [2]=>
  string(65) "scheduleReportResponse scheduleReport(scheduleReport $parameters)"
  [3]=>
  string(59) "deleteReportResponse deleteReport(deleteReport $parameters)"
  [4]=>
  string(62) "getReportListResponse getReportList(getReportList $parameters)"
}


Fatal error: Uncaught SoapFault exception: [soap:Client] Error reading XMLStreamReader. in /home/a2op/public_html/billing/sp/index.php:11 Stack trace: #0 /home/a2op/public_html/billing/sp/index.php(11): SoapClient->__soapCall('getReportList', Array) #1 {main} thrown in /home/a2op/public_html/billing/sp/index.php on line 11

What am I doing wrong here?

EDIT

When debugging via

try {
    var_dump($sp->getReportList());
} catch (SoapFault $exception) {
    var_dump($exception->getMessage());
    var_dump($exception);
}

, this is the error dump

XML output after running

try{
    var_dump($sp->getReportList());
}catch (SoapFault $exception) {
    var_dump($exception->getMessage());
    var_dump($exception);

Interesting: never used it before, but I think that this is wrong:

$header = new SoapHeader('[companyId]', '[username]', '[password]');
$sp->__setSoapHeaders($header);

I think you want this:

$headers = array();
$header[] = new SoapHeader('webobjects.reporting.pbap.spmd.com', 'username', '[username]');
$header[] = new SoapHeader('webobjects.reporting.pbap.spmd.com', 'password', '[password]');
$header[] = new SoapHeader('webobjects.reporting.pbap.spmd.com', 'companyId', '[companyId]');
$sp->__setSoapHeaders($headers);

see http://www.php.net/manual/en/soapclient.setsoapheaders.php for the setSoapHeaders() multiple header call and you should probably dump out the request XML to verify that it looks like the example at http://advertising.superpages.com/spapiweb/v2?wicket:interface=:11:3: .

Let me know if it works.
