if you haven't (yet) disabled caps-lock, this is one thing it's
typically used for -- successful strings of capital letters.
Anyway, if you use $_SESSION[] a lot, then creating a short 2-char
function can be helpful. Someone else coming along later to maintain
your code might be highly mystified about it though.

You should add in a check to make sure the $_SESSION[$var] actually
exists as an index in your first return statement and return a value
you can check against for success/failure.

This would be the safest way in this case. I'm not 100% how this would
devolve into byte-code, but my assumption is that there would be a
very slight performance cost, however, since you are calling a
function for every access to the $_SESSION array, you've already bit
the majority of that cost.

All in all, I would not use this sort of aliasing of a function to an
array to save typing. Get an IDE if it really is that onerous. I can
type ses<tab> and it expands to $_SESSION['index'] automatically
dropping me at the first apostrophe with the whole inner string
highlighted. Saves *LOTS* of typing.
