Thais kind of error does NOT occur at PHP4.1 for Win32, but I have no opportunity to check it at the same version PHP for FreeBSD.

Example:

<?
$group = array(array(1, 2, 3), array(4, 5, 6));
$count = 2;
for ($c = 0; $c < $count; $c++) {
  reset($group);
  while (list($i) = each($group)) {
    list($key, $val) = each($group[$i]);
    echo "$val ";
  }
}
?>

That scrips produces "1 4 2 5 " at PHP4.1.0@Win32
but "1 4 1 4" at PHP4.0.6@FreeBSD4.3
