Would $var[-2] be strlen($var) - 2 and so on? And then one would expect some rather complex logic to compute -N for $var[-N] At that point, this becomes a pretty big WTF, imho. I've never honestly felt it to be a big burden to use strlen($var) - 1, so I don't really see the point, at least for me. -- brain cancer update: http://richardlynch.blogspot.com/search/label/brain%20tumor Donate: https://www.paypal.com/cgi-bin/webscr?cmd=_s-xclick&hosted_button_id=FS9NLTNEEKWBE
