No, Christopher, that is not a bug. As long as the var is empty, and if
you try to compare with 0, or false, it will report true in the
comparison because the variable does not contain anything, which will
mean false for a boolean and 0 for a variable. If you are attempting to
discover if a string contains data, use empty() instead. You can also
check if the string is null or actual zero (0).
Regards,
Torgny
