Seems to me that
$str = substr($str,1);
is about as fast, straight-forward, and easy to understand
as i need. I would only use reverse if i needed to reverse
the string ... but this is better used in conjunction with
a regex (see
sexeger).
If you would like to see a more obscure way, how about using
split and join? (don't try this at work)
$str = join('',(split('',$str))[1..length($str)]);
