I am having a huge headache.  I am doing this in SoapUI:

DESIRED CALL / REQUEST

        <soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
         xmlns:own="www.ownyourliferewards.co.za"
         xmlns:own1="http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.WebServicesBase"
         xmlns:own2="http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.Generic.DataObjects">
           <soapenv:Header/>
           <soapenv:Body>
              <own:AuthenticateMember>
                 <!--Optional:-->
                 <own:request>
                    <!--Optional:-->

<own1:SecurityToken>9415CD31-0C7E-40AB-A45F-D3538B98B96B</own1:SecurityToken>
                    <!--Optional:-->
                    <own2:MembershipNumber>200803407801</own2:MembershipNumber>
                 </own:request>
              </own:AuthenticateMember>
           </soapenv:Body>
        </soapenv:Envelope>

I am doing the following in PHP and Nusoap:

    <?php
    require_once('nusoap.php');
    $client = new
nusoap_client('https://integrationqa.ownyourliferewards.co.za/RTService.svc?wsdl',
'wsdl');
    $client->soap_defencoding='utf-8';
    $err = $client->getError();

    if ($err) {
        echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
    }

    $param = array('request'=> array('MembershipNumber' =>
'200803407801', 'SecurityToken' =>
'9415CD31-0C7E-40AB-A45F-D3538B98B96B' ));
    $result = $client->call('AuthenticateMember', $param);
    if ($client->fault) {
        echo '<h2>Fault</h2><pre>';
        print_r($result);
        echo '</pre>';
    } else {
        // Check for errors
        $err = $client->getError();
        if ($err) {
            // Display the error
            echo '<h2>Error</h2><pre>' . $err . '</pre>';
        } else {
            // Display the result
            echo '<h2>Result</h2><pre>';
            print_r($result);
            echo '</pre>';
        }
    }
    echo '<pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre>';

WHAT I AM GETTING WITH THE ABOVE CODE:

    <?xml version="1.0" encoding="utf-8"?>
    <SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
        <SOAP-ENV:Body>
            <AuthenticateMember xmlns="www.ownyourliferewards.co.za">
                <request>
                    <MembershipNumber>200803407801</MembershipNumber>

<SecurityToken>9415CD31-0C7E-40AB-A45F-D3538B98B96B</SecurityToken>
                </request>
            </AuthenticateMember>
        </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>

As you can see, there are some important bits missing.

1) The `own:`, `own1:`, and `own2:` "namespaces" (if that is what they
are) are missing.

2) There is no header as per the desired example.

Any kind of fix or workaround will be sincerely appreciated.

UPDATE:

I have now been able to get the request to look like this:

        <?xml version="1.0" encoding="utf-8"?>
        <SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
         xmlns:own="www.ownyourliferewards.co.za"
         xmlns:own1="http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.WebServicesBase"
         xmlns:own2="http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.Generic.DataObjects"
         xmlns:ns5813="http://tempuri.org">
            <SOAP-ENV:Body>
                <AuthenticateMember xmlns="www.ownyourliferewards.co.za">
                    <request>
                        <MembershipNumber>200803407801</MembershipNumber>

<SecurityToken>9415CD31-0C7E-40AB-A45F-D3538B98B96B</SecurityToken>
                    </request>
                </AuthenticateMember>
            </SOAP-ENV:Body>
        </SOAP-ENV:Envelope>

by adding

    $client->namespaces =
array('SOAP-ENV'=>"http://schemas.xmlsoap.org/soap/envelope/",
'own'=>"www.ownyourliferewards.co.za",
'own1'=>'http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.WebServicesBase',
'own2'=>'http://schemas.datacontract.org/2004/07/OwnYourLife.WebServices.Generic.DataObjects');

The final remaining issue I have is this:

How do I "inject" those namespaces so that the xml looks like this:

    <own:AuthenticateMember xmlns="www.ownyourliferewards.co.za">
        <own:request>
            <own1:SecurityToken>9415CD31-0C7E-40AB-A45F-D3538B98B96B</own1:SecurityToken>
            <own2:MembershipNumber>200803407801</own2:MembershipNumber>
        </own:request>
    </own:AuthenticateMember>

Please, can anyone assist?
