What is difference between phpredis and predis in laravel?

PhpRedis is a PHP extension for communicating with the Redis storage.

Predis is the alternative for PhpRedis on pure PHP and does not require any additional C extension by default, but it can be optionally paired with phpiredis.

I will recommend that phpredis provide a lot of better performance.

Google says:

The PHP clients officially recommended by redis are predis and PHP redis. The former is a native client implemented entirely in PHP code, while the latter is a PHP extension written in C. There is little difference in function between the two, and the latter is better in performance. Although predis performs worse than phpredis, it is difficult to distinguish the performance of predis from that of phpredis unless a large number of redis commands are executed. Moreover, the cost of executing redis commands in practical applications is more on network transmission, and it is not significant to focus solely on the performance of the client.

I myself always use PHPREDIS
