Example: ¶

Case A: Subscribe/Publish

1, mqtt client subscribe topic: room/count/100011

2.1, mqtt client publish: every time publish topic: room/join/100011, the subscribe side will get count+1, or publish topic: room/leave/100011 get count -1.

2.2, redis client pulish: every time $redis->publish('async', 'room/join/100011'), the subscribe side will get count+1, or $redis->publish('async', 'room/leave/100011') get count -1.

Case B: Publish(Notification Or Report)

mqtt client publish topic: report/coord/100111 and payload: e.g. 110.12345678,30.12345678,0,85

Coding: ¶

MQTT subscribe topic: "channel/count/100001" will handle at: `

class ChannelController{
    public function actionCount($channel_id){
        echo "client {$this->fd} subscribed the count change of channel {$channel_id}";
    }
}

> //client 1 subscribed the count change of channel 100001


MQTT Publish Topic:  "channel/join/100001"  with payload: "Foo"  will handle at:

class ChannelController{
    public function actionJoin($channel_id, $who){
        echo "{$who} join in channel {$channel_id}";
        #then broadcast update to all client who subscribed channel 100001
        #$this->publish($fds, $sub_topic, $count);
    }
}

> // Foo join in channel 100001
