I've posted a new php example to:

ftp://ftp.novell.com/outgoing/phpSOAP.ZIP

I used a later version of php (5.3.5) and wsdl2php (0.2.1).
I had to make some hand modifications to GroupwiseService.php.

Again it is just a proof of concept.
Let me know if you have problems or need additional examples.

After I get feedback (if any), I'll post it to the sdk website.

Thanks.
Preston
