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.
