Why check both isset() and !empty()

Question

Is there a difference between isset and !empty. If I do this double boolean check, is it correct this way or redundant? and is there a shorter way

Answer 1

The accepted answer is not correct.

isset() is NOT equivalent to !empty().

You will create some rather unpleasant and hard to debug bugs if you go down this route. e.g. try running this code:
