[`php-mqtt/client`](https://packagist.org/packages/anviz/php-mqtt-client) was created by, and is maintained by [Jacobs](https://github.com/AnvizJacobs). It allows you to connect to an MQTT broker where you can publish messages and subscribe to topics. The implementation supports all QoS levels ([with limitations](#limitations)

Installation
------------

[](#installation)

```
composer require anviz/mqttclient
```

This library requires PHP version 7.2 or higher.

Usage
-----

[](#usage)

#### Publish

[](#publish)

A very basic publish example requires only three steps: connect, publish and close

```
$clientId = 'test-publisher';

$mqtt = new MQTTClient($server, $port, $clientId);
$mqtt->connect();
$mqtt->publish('php-mqtt/client/test', 'Hello World!', 0);
$mqtt->close();
```

If you do not want to pass a `$clientId`, a random one will be generated for you. This will basically force a clean session implicitly.

Be also aware that most of the methods can throw exceptions. The above example does not add any exception handling for brevity.

#### Subscribe

[](#subscribe)

Subscribing is a little more complex than publishing as it requires to run an event loop:

```
$clientId = 'test-subscriber';

$mqtt = new MQTTClient($server, $port, $clientId);
$mqtt->connect();
$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message) {
    echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
}, 0);
$mqtt->loop(true);
```

While the loop is active, you can use `$mqtt->interrupt()` to send an interrupt signal to the loop. This will terminate the loop before it starts its next iteration. You can call this method using `pcntl_signal(SIGINT, $handler)` for example:

```
pcntl_async_signals(true);

$clientId = 'test-subscriber';

$mqtt = new MQTTClient($server, $port, $clientId);
pcntl_signal(SIGINT, function (int $signal, $info) use ($mqtt) {
    $mqtt->interrupt();
});
$mqtt->connect();
$mqtt->subscribe('php-mqtt/client/test', function ($topic, $message) {
    echo sprintf("Received message on topic [%s]: %s\n", $topic, $message);
}, 0);
$mqtt->loop(true);
$mqtt->close();
```

Features
--------

[](#features)

- MQTT Versions
    - v3.1
    - v3.1.1
    - v5.0
- Transport
    - TCP (unsecured)
    - TLS (secured, verifies the peer using a certificate authority file)
- Connect
    - Last Will
    - Last Will Topic
    - Last Will Message
    - Required QoS
    - Message Retention
    - Authentication (username & password)
    - Clean Session (can be set and sent, but the client has no persistence for QoS 2 messages)
- Publish
    - QoS Level 0
    - QoS Level 1 (limitation: no persisted state across sessions)
    - QoS Level 2 (limitation: no persisted state across sessions)
- Subscribe
    - QoS Level 0
    - QoS Level 1
    - QoS Level 2 (limitation: no persisted state across sessions)
- Supported Message Length: unlimited *(no limits enforced, although the MQTT protocol supports only up to 256MB which one shouldn't use even remotely anyway)*
- Logging possible (`Psr\Log\LoggerInterface` can be passed to the client)
- Persistence Drivers
    - In-Memory Driver
    - Redis Driver

Limitations
-----------

[](#limitations)

- There is no guarantee that message identifiers are not used twice (while the first usage is still pending). The current implementation uses a simple counter which resets after all 65535 identifiers were used. This means that as long as the client isn't used to an extent where acknowledgements are open for a very long time, you should be fine. This also only affects QoS levels higher than 0, as QoS level 0 is a simple fire and forget mode.
- Message flows with a QoS level higher than 0 are not persisted as the default implementation uses an in-memory repository for data. To avoid issues with broken message flows, use the clean session flag to indicate that you don't care about old data.
