Linux, Apache, MySQL, PHP

I'm stuck with this problem, any help will be appreciated.

I have a web service, it requires authentication to call functions but I couldn't authenticate.

The function XML is like this:

    <s11:Envelope xmlns:s11='http://schemas.xmlsoap.org/soap/envelope/'>
      <s11:Header>
        <ns1:AuthHeader xmlns:ns1='MOD'>
    <!-- optional -->
          <ns1:Channel>?XXX?</ns1:Channel>
    <!-- optional -->
          <ns1:Username>?XXX?</ns1:Username>
    <!-- optional -->
          <ns1:Password>?XXX?</ns1:Password><!-- This element can be extended by any attribute from any namespace -->
        </ns1:AuthHeader>
      </s11:Header>
      <s11:Body>
        <ns1:GetBankList xmlns:ns1='MOD' />
      </s11:Body>
    </s11:Envelope>

my connection codes are:

    $baglanti = new :confused:SoapClient("https://galaksi.turknippon.com/appservice/mod.asmx?wsdl");
    $parm = array();
    $parm[] = new SoapVar('channelcode', XSD_STRING, null, null, 'Channel' );
    $parm[] = new SoapVar('myusername', XSD_STRING, null, null, 'Username' );
    $parm[] = new SoapVar('mypassword', XSD_STRING, null, null, 'Password' );

    $Adres = "https://galaksi.turknippon.com/appservice/";
    $Baslik =  new SoapHeader($Adres, "AuthHeader",new SoapVar($parm, SOAP_ENC_OBJECT));
    $baglanti->__setSoapHeaders(array($Baslik));
    $sonuc = $baglanti->AuthHeader(new SoapVar($parm, SOAP_ENC_OBJECT));
    print_r ($sonuc);

Here is a stack trace:
