What happens if you included only the method in the call?: $results = $soap->call($method, $soapenv);

answer: I get a SOAP envelope going to the web service with munged up XML. For example:

<soap:Envelope ...>
<soap:Body> ...
 <c-gensym2><?xml version="1.0" encoding="UTF-8">
<soap:Envelope ...>
<soap:Header> ...
</soap:Header>
<soap:Body> ...
</soap:Body>
</soap:Envelope>
</c-gensym2>
</soap:Body>
</soap:Envelope>
