Informations about the package php-mqtt-client
PhPMqttClient
MQTT 3.1.1 Client with TSL support in PHP
Note that all calls are blocking until a timeout occurs. If you need some fancy async solution, you'll have to find another repo.
This implementation works with MQTT ver 3.1.1 for QOS levels 0 and 1. QOS level 2 should work, but is experimental until better tested.
Installation
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist karpy47/php-mqtt-client
or add
"karpy47/php-mqtt-client": "*"
to the require section of your composer.json.
Requirements
Should work with all recent PHP versions.
Code developed and running in production using PHP v7.0.27 (previously also PHP v5.6.27)
Basic Usage
use karpy47\PhpMqttClient\MQTTClient;
$client = new MQTTClient('mqtt-server.domain.com', 8162);
$client->setAuthentication('mqtt-server.username','mqtt-server.password');
$client->setEncryption('cacerts.pem');
$success = $client->sendConnect(12345); // set your client ID
if ($success) {
$client->sendSubscribe('topic1');
$client->sendPublish('topic2', 'Message to all subscribers of this topic');
$messages = $client->getPublishMessages(); // now read and acknowledge all messages waiting
foreach ($messages as $message) {
echo $message['topic'] .': '. $message['message'] . PHP_EOL;
// Other keys in $message array: retain (boolean), duplicate (boolean), qos (0-2), packetId (2-byte integer)
