                                'SurveyorID' => '23',
                                'RRN' => '0240-9002-0391-3520-0020',
                                'NewInstruction'=> 'true',
                                'StatusID' => '1'
                                );
                $result = $client->__soapCall("UpdateInstruction", $params );

                print_r(    $result);

    ?>

i have got this error Fatal error: Uncaught SoapFault exception: [soap:Server] Server was unable to process request. ---> Object reference not set to an instance of an object. in C:\\xampp\\htdocs\\test2.php:33 Stack trace: #0 C:\\xampp\\htdocs\\test2.php(33): SoapClient->__soapCall('UpdateInstructi...', Array) #1 {main} thrown in C:\\xampp\\htdocs\\test2.php on line 33

Answer 1

You probably need to send something like:

 $result = $client->__soapCall("UpdateInstruction", array('Instruction' => $params );

Where Instruction is the name of the object that you are passing.

Answer 2

It looks like a NullReferenceException was thrown on the server side. So, it's a matter of the parameters to whatever function is occurring on the server side generating that error.

Regardless of why, per best practices, this is an error in the .NET service. The NullReferenceException should really be replaced with something more specific.

Can you get in touch with whomever wrote the service to get more information to troubleshoot? It's quite possible that you have a parameter misnamed in your $params array, but you're probably going to need some help from the service writer.
