[PHP] SOAP function call

[Craig Gardner]

I'm trying to create a simple (I think) SOAP function that checks 
whether or not a file was uploaded to a server.  I have everything set 
up, but when I try to use the function I get an array disguised as an 
object.  The function I've created should return either TRUE or FALSE 
and I can't find either result in the array.  What am I doing wrong?

Thanks,

Craig.

Server:

<?php
require_once('SOAP/Server.php');
class validate
{
       var $method_namespace = 'urn:validate';
       function check($filename)
       {
               if(file_exists($filename))
               {
                       $return = "TRUE";
               }
               else
               {
                       $fp = fopen($filename, "a");
                       $contents = fread($filename, filesize($filename));
                       if(!strstr($contents, $filename))
                               fwrite($fp, $filename."/r/n");
                       fclose($fp);

                       $return = "FALSE";
               }
               return $return;
       }
}
$check = new validate;

$server = new SOAP_Server;
$server->addObjectMap($check);
$server->service($HTTP_RAW_POST_DATA);
?>

Client:

require_once("SOAP/Client.php");
$soap = new SOAP_Client('http://10.0.1.100/scanned_docs/index.php');
$params = array("filename" => $tmpname);
$urn = "urn:validate";
$obj = $soap->call('verify', $params, $urn)
