Possible values for boolean variables are “1” and “0” (meaning “TRUE” and “FALSE”).

Everything else is evaluated to one of these values by PHP: Non-empty strings (except “0” [zero]) are treated as “TRUE”, empty strings are evaluated to FALSE.

Examples:

dummy.enable = 0            # false, preferred notation
dummy.enable = 1            # true, preferred notation
dummy.enable =              # false, because the value is empty
