isset on null var

[bike5]

Is it possible to get a true returned on the existence of a variable that is null? While at the same time getting a false returned if the variable does not exists. I either get undefined returning the same value as null variables or I get a notice error, I just want to verify that the null variable exists opposed to the variable not existing without throwing a notice error. Thanks.

Null is not a variable, it is a type. Null and false are two different things as well.

Can you post the code you are having problems with so we can clarify the issue?

isset($var) returns false (looking for true but isset returns false even when its set but the value is null)

every other function empty, is_null ect either returns the same result for undefined and (defined and null) or throws an error when its undefined and true when null.
