Reading Web Service using PHP with GUID and Namespace - php

Question

I am new to Web Services and am struggling to access/read the XML data using PHP (my website that will be using the data is in PHP).
The WSDL Url: http://services.mywheels.co.za/BWAVehicleStockService.svc?wsdl
I need to get access and read the Vehicle stock information but cant see to access anything.
the Array vehicle are stored under: http://services.mywheels.co.za/BWAVehicleStockService.svc?xsd=xsd2 .
i am using this code but it doesnt give my any data. I also have a GUID that i need to pass but have no idea how to add it to the header.
<?PHP
define('NEWLINE', "<br />\n");
// SOAP client
$wsdl = 'http://services.mywheels.co.za/BWAVehicleStockService.svc?wsdl';
$soapClient = new SoapClient($wsdl, array('cache_wsdl' => 0));
// SOAP call
$parameters->ArrayOfVehicle->Vehicle;
try
{
$result = $soapClient->GetVehicleStock($parameters);
}
catch (SoapFault $fault)
{
echo "Fault code: {$fault->faultcode}" . NEWLINE;
echo "Fault string: {$fault->faultstring}" . NEWLINE;
if ($soapClient != null)
{
$soapClient = null;
}
exit();
}
$soapClient = null;
echo "<pre>\n";
print_r($result);
echo "</pre>\n";
echo "Return value: {$result->GetDataResult}" . NEWLINE;
?>
if someone can help or point me in the right direction with this that would be great.
Thanks

You can add headers using __setSoapHeaders():
$h = new SoapHeader('http://tempuri.org/', 'Guid', '123');
$soapClient->__setSoapHeaders($h);
I had to read the WSDL itself to find out what namespace I should use; in this case they refer to Guid as tns:Guid and from the top you can read what URI is used to express that, hence http://tempuri.org.
