PHP Soap Error: The server was unable to process the request. ---> The reference to the object is not installed in the instance of the object

Question

I am using PHP 5.2.5.5 with Moodle 1.9.

When I make a simple SOAP call without parameters, it works. However, as soon as I use a call with a parameter, it fails. If I capture a SOAP request using Fiddler, I see that it does not add a parameter to the soap request at all.

Here is my sample code:

$WSDL = 'http://www.nanonull.com/TimeService/TimeService.asmx?WSDL';
$client = new SoapClient($WSDL);
$response = $client->getUTCTime(); // WORKS
$response = $client->getTimeZoneTime('ZULU');  // SOAP FAULT

Any suggestions?

You also need to pass the name of this parameter (and pass the array):

$WSDL = 'http://www.nanonull.com/TimeService/TimeService.asmx?WSDL';
$client = new SoapClient($WSDL);
$response = $client->getUTCTime(); // WORKS

$response = $client->getTimeZoneTime(array('timezone'=>'ZULU')); //works
print_r( $response);
