##phpredis and predis

phpredis is a PHP extension written in C, and predis is written in pure PHP.

The difference in performance is of course better expansion, but in fact there is a bigger difference between the two implementations, which is the maintenance of connections.

1. phpredis uses c in the extension to maintain a long connection from php-fpm to redis, so multiple requests on a php-fpm process reuse the same connection. Pconnect of phpredis is a long connection method.

2. Predis uses PHP socket to connect to redis, so you need to connect to redis every time you request it.

It can be seen that Laravel officially recommends using predis. Because of the pure PHP implementation, only composer can be installed, which is very consistent with Laravel's convenient thinking.

The performance gap between phpredis and predis does not span orders of magnitude. Of course, the specific business must be considered. If the business relies heavily on redis and the single-machine QPS needs to support a relatively large amount, it is recommended to use phpredis. If you only use laravel and redis to implement small-scale business, it is recommended not to change predis.
