Update prepend.inc add human logic function

[ahilespelid]

it is known that 'is_scalar' does not skip 'null', but the documentation indicates that some resources may be skipped in the future, and since hypothetically a resource can return 'null', the code uses an excessive check for null '$logic_parametr ?? 0'. If you look under the hood of filter_var FILTER_VALIDATE_BOOLEAN, it is known that null returns false, so this construction is '$logic_parametr ?? 0' is redundant and must be replaced by '$logic_parametr'

Thank you for your contribution, but where should the method added here be used?
