This seems simple enough for a hard-coded -1, but...

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.
