just as well for UTF-8 usages = I meant also for NONE UTF-8 usages (to keep the numbers unchanged)

/*

Here's a function that adds to carmel.alex's utf-8 encoding support the ability NOT to reverse numbers (for example when you output a phrase as a parameter for a SWF file that can't handle RTL languages itself, but obviously any numbers should remain the same as in the original phrase).



Note that it can be used just as well for UTF-8 usages if you want the numbers to remain intact:

function utf8_strrev($str, $reverse_numbers) {

  preg_match_all('/./us', $str, $ar);

  if ($reverse_numbers)

    return join('',array_reverse($ar[0]));

  else {

      $temp = array();

      foreach ($ar[0] as $value) {

         if (is_numeric($value) && !empty($temp[0]) && is_numeric($temp[0])) {

            foreach ($temp as $key => $value2) {

               if (is_numeric($value2))

                 $pos = ($key + 1);

               else

                  break;

            }

            $temp2 = array_splice($temp, $pos);

            $temp = array_merge($temp, array($value), $temp2);

         } else

            array_unshift($temp, $value);
