pear soap client parameter question - it makes me crazy

Hi! I've made a (PEAR) SOAP client like this:

	$WSDL     = new SOAP_WSDL($wsdl_url);

$client = $WSDL->getProxy(); $result = $client->thisIsTheService($text); My problem is that this won't work (soap fault), if I set the: $text = $_REQUEST['text']; but it will if I set the: $text = "Sample text"; What is the difference between them and how can I set it to work? ($_REQUEST['text'] . " " and such does not work. The text parameter seems ok if I echo it, the type is string..) Thank you: Istvan
