I have create WCF service Project. I can consume from .NET framework. I can pass a variable and can get return variable while consume from PHP. But I cannot consume that service when pass class object to service from PHP.

This is PHP code which used to call WCF service

<?php

try{
  $client = new SoapClient("http://localhost:1236/WebSite/Service.svc?wsdl");

// Set parameters
$parms['CompMember']['MemberAge'] = 'Member Name';
$parms['CompMember']['MemberID'] ="123";
$parms['CompMember'] ['MemberName']= 25;

// Call web service PassMember methordd
 $webService = $client-> PassMember($parms);
 $wsResult = $webService->PassMemberResult();
 
// print response
 print_r($wsResult);
       
       } catch (Exception $e) {
       echo 'Caught exception:',  $e->getMessage(), "\n";
}  
// -----------------------------------------------------

try{
  $client = new SoapClient("http://localhost:1236/WebSite/Service.svc?wsdl");
 


// Set parameters
$parms['Student']['Alsubject']['SubID']  = 'AL002';
$parms['Student']['Alsubject']['SubName']  = 'MATHS';
$parms['Student']['Alsubject']['SubResult']  = 'A';
$parms['Student']['StudID'] ="123";
$parms['Student'] ['StudName']= 'Student Name';
$parms['Student'] ['studAge']= 25;

// Call web service PassMember methordd
 $webService = $client-> getVal($parms);
 $wsResult = $webService->getValResult();
 
// print response
 print_r($wsResult);
       
       } catch (Exception $e) {
       echo 'Caught exception:',  $e->getMessage(), "\n";
}
?>

When we call service via PHP We have exception
"Caught exception: Object reference not set to an instance of an object."

If someone know solve this problem Please let me know.
