php-mqtt / client-examples Goto Github PK

Hi

I am attempting to integrate this with my website. but I keep getting errors on the require . I can see the files listed in c:\users\Administrator\Vendor

So I tried ..

require 'C:/users/Administrator/vendor/autoload.php';
require DIR . '/SimpleLogger.php';

use PhpMqtt\Client\src\Exceptions\ConnectingToBrokerFailedException;
use PhpMqtt\Client\src\Exceptions\DataTransferException;
use PhpMqtt\Client\src\Exceptions\UnexpectedAcknowledgementException;

I also attempted to copy the mentioned files directly to my website folders also get errors..

Is there a tutorial of how to install and configure???

Regards

I installed php-mqtt using composer, but I could not load the class.

require 'vendor/autoload.php';
use \PhpMqtt\Client\MqttClient;

$server   = 'localhost';
$port     = 1883;
$mqtt = new \PhpMqtt\Client\MqttClient($server, $port);

It always throws this error: PHP Fatal error: Uncaught Error: Class 'PhpMqtt\Client\MqttClient' not found.

Is there anything else needed to make it work.

Note that I use CentOS 8 server.

Hello,
I'm trying to subscribe to a mosquitto broker using the given examples but it cant connect, it's either a 500 error or a timeout. Note publishing works without issues. I have used https://github.com/php-mqtt/client-examples/blob/master/02_subscribing/03_subscribe_with_qos_2.php but failed so i was wondering if this a case of outdated code. Any help would be great. Thanks !

I am publishing a message with:

$client->publish('foo/bar/baz', 'Hello world!', MqttClient::QOS_AT_LEAST_ONCE);

How do I check if the message was confirmed and PUBACK was sent back?

I am using aws iot mqtt broker to connect, but getting this error:

[4] Establishing a connection to the MQTT broker failed: The broker did not acknowledge the connection attempt within the configured connection timeout period.

<?php

use PhpMqtt\Client\MqttClient;
use PhpMqtt\Client\ConnectionSettings;

$client = new MqttClient("aws-iot-endpoint", "8883", 'aws-iot-client-id', MqttClient::MQTT_3_1_1);

// Create and configure the connection settings as required.
$connectionSettings = (new ConnectionSettings)
    ->setUseTls(true)
    ->setTlsSelfSignedAllowed(true)
    ->setTlsClientCertificateFile("aws-device-certificate")
    ->setTlsClientCertificateKeyFile("aws-private-key");

// Connect to the broker with the configured connection settings and with a clean session.
$client->connect($connectionSettings, true);

// Publish the message 'Hello world!' on the topic 'foo/bar/baz' using QoS 0.
$client->publish('foo/bar/baz', 'Hello world!', MqttClient::QOS_AT_MOST_ONCE);

// Gracefully terminate the connection to the broker.
$client->disconnect();

Hi,
Sorry, my background is C++ and I am trying to leave subscription loop if there's no data within 5 seconds.

I have look at this code but no idea how to set loop timeout.
