 by default $_GET/$_POST can be string|array type.

 All sanitize functions accept only string, which makes it necessary to
 validate $_GET/$_POST for `is_string` all the time before calling sanitize
 function to avoid PHP notices.

 Instead sanitize function should accept mixed param and validate string
 internally.
