Use SOCKET to operate redis

 

Code:

$cmd = "*3\r\n$3\r\nSET\r\n$3\r\nfoo\r\n$3\r\nbar\r\n"; // set foo bar$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);socket_connect($socket, ‘127.0.0.1‘, 6379);$flag = socket_write($socket,$cmd,strlen($cmd));eee($flag);

 

Reids protocol uses text protocol

In addition to the native TCP protocol, redis also designedInline commandsTo operate redis like in redis-cli

 

Redis: Text Protocol

Memcached: text protocol + binary Protocol

HTTP: Text Protocol

Gearman: Binary Protocol

MySQL: Binary Protocol

 

Binary Protocol: smaller data volume, higher efficiency, but not easy to expand, poor readability

Text Protocol: multiple data transmission, good readability, and easy scalability

 

Predis is an extension that uses the native socket method to operate redis.
