If I understand you correctly, you only want the leaves of your tree - in your example, that would be 20? I don't think there's a convenient builtin function that'll do it, but it's not hard to write your own: <?php function leaf_count($item) { $count = 0; if (!is_array($item)) { return 1; } foreach ($item as $element) { $count += leaf_count($element); } return $count; } print leaf_count($array); ?>
