Bug description:  array_rand does not return keys randomly

I called array_rand($my_array, count($my_array)). I expected array_rand to
return the keys of $my_array in random order. I actually received the keys
in almost the same order each time. $my_array was a 4 element array and
the third element's key never changed position. I tried using srand also,
but it produced same results. On an older version of php(4.1.2) the
function worked as expected.

script on WinXP php4.2.3:
$numbers = range (1,4);
$rand_keys = array_rand ($numbers, count($numbers));
foreach ($rand_keys as $val) {
   print $numbers[$val]."\n";
}
