I agree. If we can have one function to check this, it would be better than writing PHP hacks. Any language that don't enforce variable declaration, should have a well defined way to check whether a variable exists or not. And we are talking about the variable, not the value it stores. :)
Don't use nulls as values and you won't have to use hacks. null is not a value, was never meant to be a value, and won't be a value.
