In PHP, you could use Redis to cache data to provide faster access. The hit/miss ratio - the number of successful lookups ('hits') versus unsuccessful ('misses') - can help gauge the effectiveness of your caching strategy.
info method to get cache stats
info method provides various statistics about the state of the Redis server, including hits and misses.
This script first connects to the Redis server, then retrieves the info. It gets the hits and misses, calculates the ratio, and finally prints it out.
1. What does a high hit/miss ratio mean in Redis? A high hit/miss ratio indicates that most of the requested keys are available in the Redis cache, resulting in fast data access. This generally means your caching strategy is effective.
2. What if my hit/miss ratio is low? A low hit/miss ratio suggests that many requests aren't being served from the cache and are instead going to the database. This could indicate that your caching strategy needs improvement.
