Here's the code:

 36 | $base == 10) {
      echo 'BASE must be in the range 2-9 or 11-36';
      exit;
   } // if

   // maximum character string is 36 characters
   $charset = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';

   // strip off excess characters (anything beyond $base)
   $charset = substr($charset, 0, $base);

   if (!ereg('(^[0-9]{1,50}$)', trim($decimal))) {
      $error['dec_input'] = 'Value must be a positive integer with < 50 digits';
      return false;
   } // if

   do {
      // get remainder after dividing by BASE
      $remainder = bcmod($decimal, $base);

      $char      = substr($charset, $remainder, 1);   // get CHAR from array
      $string    = "$char$string";                    // prepend to output

      //$decimal   = ($decimal - $remainder) / $base;
      $decimal   = bcdiv(bcsub($decimal, $remainder), $base);

   } while ($decimal > 0);

   return $string;

}
