The example (and related documentation at redis.io) was not updated for 5 years. Redis had no sorted sets and hashes when the original code was written (!). An update was really needed. We also use a modern PHP client now: Predis. A copy is shipped within this repository to make life easier to newcomers trying Redis for the first time via this example.
