Passing by reference

So, what if I want to destroy the variable that was passed to a function?

PHP Code:

function executeFilterAction(&$message, $filter)
    {
        $subject = htmlspecialchars_uni($message['subject']);
        
        switch ($filter['tofolderid'])
        {
            case VBMS_FILTER_TOFOLDERID_DELETE:
                debugecho("Message "$subject" will be deleted");
                unset($message);
                break;
                
            case VBMS_FILTER_TOFOLDERID_MARKASREAD:
                debugecho("Message "$subject" will be marked as read");
                $message['readflag'] = true;
                break;
                
            default:
                debugecho("Message "$subject" will be moved to folderid " .
                        $filter['tofolderid']);
                $message['folderid'] = $filter['tofolderid'];
                break;
        }
        
        return false;
    } 


Note that VBMS_FILTER_TOFOLDER_DELETE case and what it does.
