Description:
------------
One-way soap requests appear to fail silently.  A one-way soap request is a request which only defines an input message, and has no output message.  When making such a soap request, the request is never sent but no errors are generated.  The call just returns.

My php configure line was:

./configure --with-curl --enable-exif --enable-soap --with-snmp --with-openssl

Here is a sample WSDL entry that fails:

<definitions name="TestSoap"
             targetNamespace="urn:TestSoap"
             xmlns:tns="urn:TestSoap"
             xmlns:xsd="http://www.w3.org/2001/XMLSchema"
             xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
             xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"
             xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
             xmlns="http://schemas.xmlsoap.org/wsdl/">

<message name="OneWayRequest">
    <part name="oneArg" type="xsd:string"/>
</message>

<portType name="TestSoapPort">
    <operation name="OneWay">
        <input message="OneWayRequest"/>
    </operation>
</portType>

<binding name="TestSoapBinding" type="tns:TestSoapPort">
    <operation name="OneWay">
      <soap:operation soapAction="urn:TestSoapAction"/>
      <input>
        <soap:body use="encoded"
                   namespace="urn:TestSoap"
                   encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      </input>
    </operation>
</binding>

<service name="TestSoapService">
    <port name="TestSoapPort" binding="tns:TestSoapBinding">
      <soap:address location="https://127.0.0.1/soap"/>
    </port>
</service>

</definitions>


Test script:
---------------
/* Using the above WSDL */

$user = 'someuser';
$password = 'password';
$client = new
     SoapClient($wsdl, array(
        "location" => "https://127.0.0.1/soap",
        "login" => "$user",
        "password" => "$password",
        "trace" => 1,
        "exceptions" => 0,
        "authentication" => SOAP_AUTHENTICATION_DIGEST
        )
     );

$result = $client->OneWay('foo');
if(is_soap_fault($result)) {
    print "SOAP Fault: (faultcode: ($result->faultcode), " .
            "faultstring: ($result->faultstring))\n";
} else {
    print_r($result);
}

exit;

Expected result:
----------------
The script should open a connection to the specified soap server and send a request to call the OneWay function.  This does not happen.

Actual result:
--------------
Fails silently -- no error, no backtrace, and no output.
