The question: Is there a way to view the XML that would be created with a PHP SoapClient function call BEFORE you actually send the request?
background:
I am
I don't believe there is a way that you'll be able to see any XML that's being created... mainly because the function is failing on it's attempt to create/pass it.
Not sure if you tried already, but if you're having trouble trying to decide what exactly you need to pass into the function you could use:
$client->__getTypes();

Hope this helps!
