Hi Erik. :)
No, you've asked for the element of $current_page_name which has the key
-1. To get the last element, probably the easiest thing to do is:
return $current_page_name[count($current_page_name) - 1];
However, a somewhat less expensive way to do it:
$path = $_SERVER['PHP_SELF'];
return substr($path, strrpos($path, '/') + 1);
(No array overhead.)

I do not know where this came from, but it just ain't so.
