I think the function would look just like the function we have for doing this. key(array_slice($arr,-2)); And no, this has no side-effect of changing the array pointer in $arr, of course. And array_last_key() is identical to array_slice($arr,-1) is it not? The only thing array_last_key() saves is a single function call to key(). That doesn't seem worth it to me. -Rasmus -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
