Hmm sounds a bit weird to me but if it's really useful than it's OK :)

    I have to agree, and its really not that hard to implement in user
    space::

    function count_recursive($ar) {
        $total = 0;

        foreach ($ar as $e => $val) {
            if (is_array($val)) {
                $total += count_recursive($val);
            }
            else {
                $total++;
            }
        }

        return $total;
    }

    To me its seems like YACFA (Yet another confusing function
    argument).

It's not hard, but it could be very *slow*... Loop and function call in PHP script is slow in general :) Since it's a O(n), so it may be okay to be slow, though. -- Yasuo Ohgaki

Why is this useful?

To count the nodes in a tree: $ar = array (

      "child1" => array ("child2", "child3", "child4"),
      "child5" => array ("child6", "child7", "child8")
    );

(maybe a louzy example, but you should get the idea :) Derick

Isn't this the function we decided to nuke?

Nope, that was is_array_multidimensional(). I'll check if it's

nuked, is

not, I'll nuke it. Derick
