// Disable magic quotes

    $process = array(&$_GET, &$_POST, &$_COOKIE, &$_REQUEST);
    while (list($key, $val) = each($process)) {

            unset($process[$key][$k]);
            if (is_array($v)) {
                $process[$key][stripslashes($k)] = $v;
                $process[] = &$process[$key][stripslashes($k)];
            } else {

            }
        }
    }
    unset($process);
}


function he($i) {
  echo htmlspecialchars($i, ENT_QUOTES);
}

function h($i) {
  return htmlspecialchars($i, ENT_QUOTES);
}

function empt($what) {
  return $what !== 0 && $what !== '0' && empty($what);
