How can send parameters to XML file using PHP with SOAP

Hi,

I want to send parameters to wsdl (xml file). I give sample code below.

--------------- createsession.php ------------------------------------------------

<?php

session_start();
require_once('lib/nusoap.php');
$client = new soapclientw('https://www.domin.com/services/umarketsc?wsdl', true);
$client->soap_defencoding = 'UTF-8';
$client->decode_utf8 = false;
$sessionResult = $client->call('createsession'); // No parameters
echo 'Session ID : '. $sessionResult;
?>
------------ End code ---------------------------------------------------------------

Sample XML for createsession
-------------------------------
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:UMARKETSCWS">
<soapenv:Header/>
<soapenv:Body>
<urn:createsession/>
</soapenv:Body>
</soapenv:Envelope>

------------------------------------

I got sessionid response from above xml file.

Another Sampe php code for Login here
--------------------------------------

----------------------login.php---------------------------------
<?php
session_start();
require_once('lib/nusoap.php');
$client = new soapclientw('https://www.domin.com/services/umarketsc?wsdl', true);
$client->soap_defencoding = 'UTF-8';
$client->decode_utf8 = false;

$username = 'webonline';
$password = '54321';

$res = strtolower($username).$password;
$res = strtolower(sha1($res));
$res = $sessionResult.$res;
$new_pin = strtoupper(sha1($res));

// below need to write login method using call function in soap

?>

----------------End code here-------------------------------------------------
