Description:
------------
I have a client and server soap which worked with php 5.1.2, but whenever i upgrade to php > 5.1.2, this code doesn't work anymore.

It's a simple client and server soap.

After debugging, the problem comes from the fact that if no <message name="funcResponse"> is provided to a function to explain the output, then this function always sends null

Even if the function throws an exception

It seems that php <= 5.1.2 was adding a default output function so that exceptions could be throwed

Reproduce code:
---------------
When using the simple client :
http://www.despatis.com/client.phps

with the simple soap server:
http://www.despatis.com/soap_server.phps

and with the wsdl:
http://www.despatis.com/Webservices.wsdl

(to make the code work, the good wsdl to use is:http://www.despatis.com/Webservices2.wsdl, however this code should work with a minimal Webservices.wsdl, that doesn't provide information on output function as the function is a void function !)

Expected result:
----------------
client.php should print:
