README

It creates a simple abstraction layer to publish and consume messages from the Redis using the component byjg/message-queue-client.

For details on how to use the Message Queue Client see the documentation

Usage

Publish

<?php
// Register the connector and associate with a scheme
ConnectorFactory::registerConnector(RedisQueueConnector::class);

// Create a connector
$connector = ConnectorFactory::create(new Uri("redis://$user:$pass@$host:$port"));

// Create a queue
$pipe = new Pipe("test");
$pipe->withDeadLetter(new Pipe("dlq_test"));

// Create a message
$message = new Message("Hello World");

// Publish the message into the queue
$connector->publish(new Envelope($pipe, $message));

Consume

<?php
// Register the connector and associate with a scheme
ConnectorFactory::registerConnector(RedisQueueConnector::class);

// Create a connector
$connector = ConnectorFactory::create(new Uri("redis://$user:$pass@$host:$port"));

// Create a queue
$pipe = new Pipe("test");
$pipe->withDeadLetter(new Pipe("dlq_test"));

// Connect to the queue and wait to consume the message
$connector->consume(
    $pipe,                                 // Queue name
    function (Envelope $envelope) {         // Callback function to process the message
        echo "Process the message";
        echo $envelope->getMessage()->getBody();
        return Message::ACK;
    },
    function (Envelope $envelope, $ex) {    // Callback function to process the failed message
        echo "Process the failed message";
        echo $ex->getMessage();
        return Message::REQUEUE;
    }
);

The consume method will wait for a message and call the callback function to process the message. If there is no message in the queue, the method will wait until a message arrives.

If you want to exit the consume method, just return Message::ACK | Message::EXIT from the callback function.

Possible return values from the callback function:

Message::ACK - Acknowledge the message and remove from the queue
Message::NACK - Not acknowledge the message and remove from the queue. If the queue has a dead letter queue, the message will be sent to the dead letter queue.
Message::REQUEUE - Requeue the message
Message::EXIT - Exit the consume method

Protocols:
