Web Service reading empty parameter - but it is not empty

[ely_pear]

Hi,
I'm unable to get this code working from php:

require 'SOAP/Client.php';
$soapclient = new SOAPClient('http://localhost/service.asmx?wsdl');
$ret = $soapclient->HelloParam( 'john' );

it should return "Hello ]john[" but for some reason it sees the parameter empty and returns "Hello ][". From another client (tired a c#one) it works fine. This happens for all the web services I try to connect to: my parameter(s) is(are) always seen as empty.

Did anyone ever experience this kind of problem?
I'm running PHP 5.1.4.

Thanks in Advance,
Ely

yes I get the same problem when passing parameters, the server says I am sending the values but they are also empty. When I remove the parameters the server returns an error saying the parameters are missing, so I know they are being sent just the values are messed up
