Php 如何使用NuSoap设置节点名称空间？

NUSOAP中有没有设置节点名称空间的方法

使用普通的PHPSOAP，它可以通过SoapVar完成

NuSoap中的等价物是什么

我有：

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

9415CD31-0C7E-40AB-A45F-D3538B98B96B
200803407801

我想：

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

9415CD31-0C7E-40AB-A45F-D3538B98B96B
200803407801

（注意节点上的own1:和own2:名称空间）

谢谢
