Forked from mix-php/redis-subscriber

A Redis native protocol Subscriber based on Swoole coroutine

A Redis native protocol subscription library based on Swoole coroutine

It connects directly to the Redis server using a Socket, independent of the phpredis extension. This subscriber has the following advantages:

• Smooth modification: Subscriptions can be added or canceled at any time, fulfilling the need for seamless channel switching.
• Safe closure across coroutines: Subscription can be closed at any moment.
• Channel message retrieval: This library's encapsulation style is inspired by the go-redis library in the Go language, retrieving subscribed messages through a channel.

Installation

composer require friendsofhyperf/redis-subscriber

Subscribing to Channels

• Connection or subscription failures will throw an exception

$sub = new \FriendsOfHyperf\Redis\Subscriber\Subscriber('127.0.0.1', 6379, '', 5); // Connection failure will throw an exception
$sub->subscribe('foo', 'bar'); // Subscription failure will throw an exception

$chan = $sub->channel();
while (true) {
 $data = $chan->pop();
 if (empty($data)) { // Manual close or abnormal disconnection from Redis will return false
 if (!$sub->closed) {
 // Handle abnormal disconnection from Redis
 var_dump('Redis connection is disconnected abnormally');
 }
 break;
 }
 var_dump($data);
}

Receiving subscribed messages:

object(FriendsOfHyperf\Redis\Subscriber\Message)#8 (2) {
 ["channel"]=>
 string(2) "foo"
 ["payload"]=>
 string(4) "test"
}
