Response from soap header

Even though i am very new to php soap concept, i write a program to communicate a web server using SoapClient.

This is my wsdl link: http://ift.tt/1GiCa8a

Service name : CreateVehicleInsurancePolicy Link : http://ift.tt/1CzNEla

I hosted my program in in an ssl certified hosting.When it run it generating a response in soap body response(lngSerial).I wanted to print the response value from soap header (SoapHeaderOut).

that is intResponseCode,strArMsg,strEnMsg.

Please guide me.Below i am providing the script which i am using.

<?php
ini_set("soap.wsdl_cache_enabled", "0");
ini_set("soap.wsdl_cache_ttl", "0");
class SOAPStruct
{
    function __construct($user, $pass) 
    {
        $this->userName = $user;
        $this->Password = $pass;

    }
}

$service = new SoapClient("http://ift.tt/1GiCa8a");
$auth = new SOAPStruct('username','password');
$header = new SoapHeader("http://ift.tt/1CzNEle","SoapHeaderIn",$auth,true); 
$service->__setSoapHeaders($header); 
$param = array('lngInsuranceCompanyCode'=> '1','intInsuranceKindCode'=>'1','lngTcf'=>'3070858641','strPolicyNo'=>'1055385883','dtExpiryDate'=>'2016-04-30T00:00:00','dtStartDate'=>'2015-03-31T00:00:00','strChassisNo'=>'6T1BE42RG465465','strRemarks'=>'demo','strUserCreated'=>'demo');

$response = $service->CreateVehicleInsurancePolicy($param)->CreateVehicleInsurancePolicyResult;

 foreach ($response as $record) {
    print_r($record);
    print_r("<br>");
  }

?>
