Using Soapclient to connect to Google Search

[iamcootis]

I'm pretty new to using the Google Search API, so I'm not exactly sure what I'm doing and kinda copied this code from somewhere else and changed it to fit my needs.
The problem is that when I connect I keep getting this error:

Fatal error: SoapClient::__call() [<a href='soapclient.--call'>soapclient.--call</a>]: first parameter must be string or null in C:\Program Files\xampp\htdocs\bandfinder\test.php on line 107

line 107 is the line that starts with $data

Any idea why this is happening? Am I not using the __call function correctly?

$params = setParams($id, $site);
$soapclient = new soapclient ('http://api.google.com/GoogleSearch.wsdl');
$data = $soapclient->__call("doGoogleSearch", $params,
		"urn:GoogleSearch", "urn:GoogleSearch");

I would stop using the deprecated method call to begin with and start using soapCall instead.

I'm not a master of SOAP; however, from the looks of it I think you have to register the function you're going to call before you actually call it.

$client = new SoapClient("some.wsdl");
$client->SomeFunction($a, $b, $c);

$client->__soapCall("SomeFunction", array($a, $b, $c));
