客户端发布

安装 composer require php-mqtt/client

use app\index\model\Temperature;
use PhpMqtt\Client\MQTTClient;



  public function mq_demo()
    {
        $server   = 'localhost';//连接地址
        $port     = 1883;//连接端口
        $clientId = 'test-publisher';//客户端ID，可随意填写，也可使用rand函数生成随机的

        $mqtt = new MqttClient($server, $port, $clientId);
        $mqtt->connect();
        $mqtt->publish('temperature', '26', 0);
        $mqtt->close();
    }

服务端订阅

 public function mqtt_sub()
    {
        $server   = 'localhost';//连接地址
        $port     = 1883;//连接端口
        $clientId = 'test-subscriber';//客户端ID，可随意填写，也可使用rand函数生成随机的

        $mqtt = new MqttClient($server, $port, $clientId);
        $mqtt->connect();
        // $mqtt->subscribe('php-mqtt/client/test', function ($topic, $message) {
        //     echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
        // }, 0);

        $mqtt->subscribe('temperature', function (string $topic, string $message) {
            // 存储温度数据到数据库
            $temperature = new Temperature;
            $temperature->value = $message;
            $temperature->save();
        });
        $mqtt->loop(true);
        $mqtt->close();
    }
