Soap Error

[star1]

HI,
I wrote a simple client in php to access soap service, when I try to run client I got following 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:\wamp\www\testsoap.php:10 
Stack trace: 
#0 [internal function]: SoapClient->__call('PlaceOrder', Array) 
#1 C:\wamp\www\testsoap.php(10): SoapClient->PlaceOrder(1, 2, 3, 4) 
#2 {main} thrown in C:\wamp\www\testsoap.php on line 10
 

Please help me to write this soap client.
Thanks

Client.php

$client = new SoapClient('http://192.168.1.74/starwstest/wmsorderfulfilment.asmx?WSDL'); 
$response = $client->CancelOrder('SOR01212')

Hi, and welcome to TSDN!

If you take a closer look at the error you just posted, it tells you exactly what went wrong and where it happened.

It tells you 'Object reference not set to an instance of an object' which means that you are trying to use an uninitialized object.
It also tells you exactly where this happens, both in the error itself and twice in the stack trace.

Take a look at line 10 in your 'testsoap.php' code and see if anything is out of place. You can post the code here if you need any help finding the problem.
