支持MQTT协议的PHP开发框架推荐

<?php

$mqtt = new MQTTClient();

// 连接到MQTT服务器
$mqtt->connect('mqtt.example.com', 1883, 60);

// 订阅主题
$mqtt->subscribe('topic/example', 0);

// 循环接收消息
while ($mqtt->loop() === true) {
    // 处理消息
    $message = $mqtt->message;
    echo "收到消息：{$message->payload}
";

    // 发布消息
    $mqtt->publish('topic/example', 'Hello, MQTT', 0);
}

// 断开与MQTT服务器的连接
$mqtt->disconnect();

?>

<?php

require('phpMQTT.php');

$mqtt = new phpMQTT('mqtt.example.com', 1883, 'phpMQTT');

// 连接到MQTT服务器
if ($mqtt->connect()) {
    // 订阅主题
    $mqtt->subscribe('topic/example', 0);

    // 发布消息
    $mqtt->publish('topic/example', 'Hello, MQTT', 0);

    // 循环接收消息
    while ($mqtt->proc()) {
        // 处理消息
        $message = $mqtt->getMessage();
        echo "收到消息：{$message['topic']} => {$message['message']}
";
    }

    // 断开与MQTT服务器的连接
    $mqtt->close();
}

?>

<?php

// 循环接收消息
while (true) {
