Bingo!
That's rather the whole point of empty and isset. :-)
The behaviour of empty has changed over time, with various releases.
isset seems more "stable" in that regard, so I prefer to use that one.
Also, to me, philosophically and from an application logic perspective, I
generally want to do something different when some variable is not set at
all, as opposed to having "" in it. But that's maybe just me. :-)
YMMV
