I have submitted a patch to support negative indexs in strings, as per
the conversation adding them to arrays could possibly detract from the
syntactical sugar they are indented to be.
In summary:
An alternative to:
$var = 'abc';
echo $var[strlen($var) - 1];
Can be:
$var = 'abc';
echo $var[-1];

Hi!
I would like to open the discussion around the support of negative
indexes, as I feel a lot of developers will benefit from this
syntactical sugar.
What you are looking for is implemented in array_slice(). Python has
shortcuts for this thing, like a[1:-1], but PHP doesn't. If you wanted
to RFC something here, I think the idea of $a[X:Y] with array_slice
semantics could be doable. $a[-1:1] would be your case then.
