I’ve always viewed arrays as an infinite field of nulls. The only time this isn’t true is when you use array_key_exists() or care about the warnings (which make it less useful, IMHO). When you treat it as an infinite field of nulls, you get some interesting mathematical/computational properties you can exploit. Trying to treat it as a map/indexed-array is when you start running into weird problems. — Rob
