Description:
------------
I have two methods test1() and test2(), but PHP always runs the first one.

You can see this on the following link:
http://www.spuetz.net/client.php
http://www.spuetz.net/source.txt

It does works, when I add a parameter (change the method signature?):
http://www.spuetz.net/client1.php
http://www.spuetz.net/source1.txt

The server is running 5.2.10 (http://www.spuetz.net/info.php), but I tried it with 5.3.0, too.

The wsdl file was generated with Zend Studio.

Reproduce code:
---------------
class Testserver {

    public function test1()
    {
        return "test1";
    }

    public function test2()
    {
        return "test2";
    }
}

[...]

var_dump($client->test1());
var_dump($client->test2());

Expected result:
----------------
string(5) "test1"
string(5) "test2"


Actual result:
--------------
string(5) "test1"
string(5) "test1"
