predisHow can I use PHP and Redis to get keys based on a pattern?

Using PHP and Redis together to get keys based on a pattern is possible by using the Redis KEYS command. The KEYS command takes a pattern as an argument and returns all the keys that match the pattern.

For example, the following code will return all keys that start with "user:".

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$keys = $redis->keys('user:*');

Output example

Array
(
    [0] => user:1
    [1] => user:2
    [2] => user:3
)

The code consists of the following parts:

1. Creating a Redis instance: $redis = new Redis();
2. Connecting to the Redis server: $redis->connect('127.0.0.1', 6379);
3. Using the KEYS command to get all the keys that match the pattern: $keys = $redis->keys('user:*');

For more information, please refer to the Redis KEYS command documentation.
