这是一个库,旨在简化PHP7和PHP8的MQTT客户端开发。
安装
composer require joserf/mqtt-php-api
目录
最低要求
php
>= 7.4
如何使用
一个非常基本的发布示例(QoS 0)只需要三个步骤:连接、发布和断开连接
按照以下示例更改字段,更改IP和端口。
发布
$server = '192.168.*.*'; $port = 1883; $clientId = 'test-publisher'; $mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId); $mqtt->connect(); $mqtt->publish('test/publisher', 'JRF API Teste!', 0); $mqtt->disconnect();
如果您不想传递一个$clientId
,将为您生成一个随机值。这基本上会强制进行隐式清理会话。
订阅
订阅比发布稍微复杂一些,因为它需要执行一个事件循环,该循环读取、分析和处理代理的消息
$server = '192.168.*.*'; $port = 1883; $clientId = 'test-subscriber'; $mqtt = new \PhpMqtt\Client\MqttClient($server, $port, $clientId); $mqtt->connect(); $mqtt->subscribe('test/subscriber', function ($topic, $message, $retained, $matchedWildcards) { echo sprintf("Received message on topic [%s]: %s\n", $topic, $message); }, 0); $mqtt->loop(true); $mqtt->disconnect();

*我们可以通过Web进行测试:
php -S localhost:8000/exemplo.php
<?php require_once __DIR__ . '/vendor/autoload.php'; error_reporting(E_ALL); use \PhpMqtt\Client\MqttClient; use \PhpMqtt\Client\ConnectionSettings; $server = '192.168.*.*'; $port = 1883; $clientId = rand(5, 15); $clean_session = true; $mqtt_version = MqttClient::MQTT_3_1_1; $connectionSettings = (new ConnectionSettings) ->setKeepAliveInterval(60) ->setLastWillMessage('client disconnect') ->setLastWillQualityOfService(1); $mqtt = new MqttClient($server, $port, $clientId, $mqtt_version); $mqtt->connect($connectionSettings, $clean_session); printf("client connected\n"); $mqtt->subscribe('mqtt/test', function ($topic, $message) { printf("Received message on topic [%s]: %s\n", $topic, $message); }, 0); $mqtt->loop(true); ?>
