function random($length, $numeric = 0) {
  $seed = base_convert(md5(microtime().$_SERVER['DOCUMENT_ROOT']), 16, $numeric &#63; 10 : 35);
  $seed = $numeric &#63; (str_replace('0', '', $seed).'012340567890') : ($seed.'zZ'.strtoupper($seed));
  $hash = '';
  $max = strlen($seed) - 1;
  for($i = 0; $i < $length; $i++) {
    $hash .= $seed{mt_rand(0, $max)};
  }
  return $hash;
