AND would be a refinement of existing criteria. Assuming ID is unique or primary, than AND would be impossible since you cannot have records with ID = 1 AND id = 2. That would use an OR.
Better yet, simply use an IN clause:
WHERE id IN ($id1, $id2, $id3, $id4) which is logically an OR grouped together.
