I appoligize, you didn't ask to find a key, in_array() searches an array's values. :P You could remove the array_keys step and switch around the foreach, but it wouldn't recurse. But, as I look at in_array, I'm not sure that recurses either. So I guess it's fine. Here's another version: function in_arrayi($needle, $haystack) { foreach ($haystack as $value) { if (strtolower($value) == strtolower($needle)) return true; } return false; } I took a shot at making one recurse, but it only went down one level. So I leave that as an exercise for somebody who knows more than I do. Matt
