So this produces an undefined index error:
Code:
if (! $_POST['does_not_exist']) // undefined index error
While empty() checks isset() first, so no error is produced:
Code:
if (empty($_POST['does_not_exist'])) // no error

I was assuming you were using a set variable as it is bad practice to just "assume" one is set/unset. But that is right.
