    [Resolved] isset() Question

    I know that isset() checks to see if a variable exists. So if I have:

    PHP Code:
    $var = '';

    if (isset(    $var)) {

    } 
    The variable exists, so will that return TRUE or FALSE? What about variables equal to NULL?

    My evil laugh has a squeak in it.
