Hello! While debuging I recognized that print_r does not output anything for bool(false) (PHP 5.2.1). e.g. <?php print_r (array (true, false, "String")); ?> Expected result: Array (
    [0] => 1
    [1] => 0
    [2] => String
) Actual result: Array (
    [0] => 1
    [1] =>
    [2] => String
) I was not quite sure whether this is expected behavior, so I haven't opened a bug yet. So, is it expected and why?

Because false is not 0. 0 evaluates to false, but so do many other things. -Rasmus
