Php SOAP Client building request - php

Question

I wanna build a request with php soap client.
The provider sent us a sample request.
here is my code;
$client = new SoapClient('http://myurl.com/TrevooWS.svc?wsdl' , array('trace' => true, 'exception' => false));
$auth_ns = 'http://schemas.datacontract.org/2004/07/Trevoo.WS.Entities.Authentication.IO';
$base_ns = 'http://schemas.datacontract.org/2004/07/Trevoo.WS.Entities.Base';
$object = new stdClass();
$form = new stdClass();
$form->Username = new SoapVar( 'USER' , XSD_STRING , null , null, 'trev1', $auth_ns);
$form->Password = new SoapVar( 'PASS' , XSD_STRING , null , null, 'trev1', $auth_ns);
$form->IsTestMode = new SoapVar( 1 , XSD_INTEGER, null , null, 'trev1', $auth_ns);
$form->ClientName = new SoapVar( 'CLIENT' , XSD_STRING , null , null, 'trev1', $auth_ns);
$form->ClientIP = new SoapVar( '0' , XSD_STRING , null , null, 'trev1', $auth_ns);
$object->request = new stdClass();
$object->request->Form = new SoapVar($form , SOAP_ENC_OBJECT, null , null, 'tem', $base_ns);
$object->request->Form->enc_namens = $auth_ns;
$object->request->Form->enc_name = 'trev1';
$object->request->enc_namens = $base_ns;
$object->request->enc_name = 'tem';
try{
$result = $client->Login( $object );
var_dump($result);
} catch (SoapFault $e){
echo $e;
var_dump($client->__getLastRequest());
var_dump($client->__getLastResponse());
}
Expected request from provider. They sent this sample request.

What I get;

I couldnt see what is wrong. Could you help me?

Answer 1

you need to order elements as expected
Ordering must be;
->ClientIP
->ClientName
->IsTestMode
->Password
->Username
