        I can use nusoap methods, then only my problem is solved

 

        require_once('nusoap.php');

 

$proxyhost = isset($_POST['proxyhost']) ? $_POST['proxyhost'] : '';

 

$proxyport = isset($_POST['proxyport']) ? $_POST['proxyport'] : '';

 

$proxyusername = isset($_POST['proxyusername']) ? $_POST['proxyusername'] : '';

 

$proxypassword = isset($_POST['proxypassword']) ? $_POST['proxypassword'] : '';

 

$client = new nusoap_client('http://......./Service.asmx?wsdl', 'wsdl',

 

$proxyhost, $proxyport, $proxyusername, $proxypassword);

 

$err = $client->getError();

 

if ($err)

{

 

echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';

 

}

 

 

// Doc/lit parameters get wrapped

$param = array('Customer' => $_GET['name']);

 

 

$result = $client->call('GetPDFDetails', array('parameters' => $param), '', '', false, true);

 

 

 

                /*  ----------------------------------------------------

                      array('parameter'=>$param) 

                      //dont change "parameter"  it's an constant and "Customer" is XML Name

 

                    -----------------------------------------------------  */
