predisHow can I use PHP and Redis to get multiple keys?

You can use PHP and Redis to get multiple keys by using the Redis::mget command. This command takes an array of keys and returns an array of values for the requested keys. For example:

$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$keys = array('key1', 'key2', 'key3');
$values = $redis->mget($keys);

print_r($values);
// Output: Array ( [0] => value1 [1] => value2 [2] => value3 )

The Redis::mget command works as follows:

1. The $keys array is passed to the Redis::mget command.
2. The Redis::mget command looks up the values for each key in the $keys array.
3. The values are returned as an array.

For more information, see the Redis documentation.
