run the following script on php3 and php4:

<?
  function reverse_key_sort($a, $b) {
      if ($a == $b) return 0; 
      return ($a > $b) ? -1 : 1;
  }
  
  $a = array(1 => 'orange', 2 => 'apple', 3 => 'bananna');

  uksort($a, reverse_key_sort);

  reset($a);
  while ( list($key, $val) = each($a) ) {
    echo "KEY=$key VAL=$val<BR>";
  }

?>

The output looks like this for php3:
KEY=3 VAL=bananna
KEY=2 VAL=apple
KEY=1 VAL=orange

And like this for php4:
KEY=1 VAL=orange
KEY=2 VAL=apple
KEY=3 VAL=bananna

Also, the only reason that I have use the uksort function is because php3 lacks a 
rksort() function (even though it has a ksort() function)  It seems like it shouldnt be to
difficult to add the rksort() function? (Cut and paste the ksort() and reverse the sorting?)
