A PHP variable can have all sorts of states, because you can take advantage of loose typing: $date = new DateTime(); $date = null; $date = 'TODAY'; $date = -1; $date = M_PI;
And isset() returns true for every one but 'null' so how do I identify a variable that isset=null?

Why do you need to, when you've got all these values to choose from? Why concentrate on the thing you can't do, when you could look at the huge array of things you can do? Yes, if exists() existed, you could use it as an extra state, but it doesn't, so you can't.
