Description:
------------
Sorry, my englisch is bad.

Problem:
I try tu use extension php_soap.dll with IIS 5.0 to build a webservice client.

If my eMail ist static $param->EmailAddress = "wase1@gtmx.net"; no problem.

If it is dynamic $param->EmailAddress = "$e"; Problem:

Fatal error:  Uncaught SoapFault exception: [soap:Server] Server was unable to process request. --> Index was outside the bounds of the array. in c:\Inetpub\wwwroot\walter\index.php:52
Stack trace:

#1 c:\Inetpub\wwwroot\walter\index.php(52): SoapClient->IsValidEMail(Object(stdClass))
#2 {main}
  thrown in c:\Inetpub\wwwroot\walter\index.php on line 52

Reproduce code:
---------------
<?
if(!empty($_REQUEST['email'])){
$WSDL='http://www.webservicex.net/ValidateEmail.asmx?WSDL';
$soapclient = new SoapClient($WSDL);

echo "<br><pre>";
$e = trim($_REQUEST['email']);
$arr = array();
$arr['EmailAddress'] = "$e";

$res = $soapclient->IsValidEMail($arr);

print_r($res);

echo "<hr>";

if(!empty($res->IsValidEMailResult))
echo "$e Is eMail";
else
echo "$e Is No eMail";

echo "</pre><br>";

}
?>
