One common use case for deleting keys in Redis using PHP includes removing outdated or no longer necessary data from the cache to maintain its efficiency.
In this example, we initialize a new Redis object and connect it to the Redis server running on localhost at port 6379. Then we delete the key named 'key'.
In this example, we delete multiple keys 'key1', 'key2', 'key3' from the Redis server. We loop over an array of keys and delete each one.
Q: What happens if I try to delete a key that doesn't exist? A: Redis will simply ignore this and continue with the execution. It won't return an error.
Q: Does the delete method work with all types of Redis keys, like lists, sets, hashes, etc.? A: Yes, the delete method can be used to remove any type of key-value pair in Redis, regardless of the data type.
