Recommended PHP development framework that supports MQTT protocol

MQTT (Message Queuing Telemetry Transport) is a lightweight publish/subscribe message transmission protocol, which is very suitable for Internet of Things and real-time messaging scenarios. In PHP development, if you need to use the MQTT protocol for message transmission, you can use some excellent PHP development frameworks to simplify the development process. This article will introduce several PHP development frameworks that support the MQTT protocol and provide corresponding code examples.

1. MQTTClient
   MQTTClient is a PHP extension based on the Mosquitto C library, which provides a complete set of MQTT client APIs. It supports MQTT v3.1 and v3.1.1 protocols and provides rich functions, such as publishing messages, subscribing to topics, maintaining connections, etc. To use MQTTClient for MQTT development, you need to install the Mosquitto C library first, and compile and install the MQTTClient extension into PHP. The following is a basic usage example of MQTTClient:

<?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();

?>

2. phpMQTT
   phpMQTT is an MQTT client implemented in pure PHP, which is more convenient to use in PHP development. It uses sockets to communicate with MQTT servers and provides a simple and easy-to-use API. phpMQTT supports the MQTT v3.1 protocol and has functions such as message publishing, subscription, and disconnection. Here is an example of using phpMQTT:

<?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();
}

?>

3. Eclipse Paho
   Eclipse Paho provides a series of MQTT client libraries based on different programming languages, including PHP. It is maintained by the Eclipse IoT project and has broad compatibility and stability. The Eclipse Paho PHP client library supports the MQTT v3.1 and v3.1.1 protocols and provides comprehensive MQTT functionality. The following is an example of using the Eclipse Paho PHP client library:

<?php

require('MQTTClient.php');

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

// 连接到MQTT服务器
$mqtt->connect();

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

// 循环接收消息
while (true) {
    $message = $mqtt->loop();
    if (!empty($message)) {
        echo "收到消息：{$message['topic']} => {$message['message']}
";
    }

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

// 断开与MQTT服务器的连接
$mqtt->disconnect();

?>

Summary:
The above are three recommended PHP development frameworks that support the MQTT protocol, namely MQTTClient, phpMQTT and Eclipse Paho . They all provide simple and easy-to-use APIs for convenient MQTT development. Choosing the appropriate framework depends on project needs and personal preferences. I hope it will be helpful to developers who use MQTT for PHP development.
