In PHP file storage, how do I consume message queues?

In this guide, we will explore how to consume message queues in PHP using various message queue services like RabbitMQ or Apache Kafka. This is essential for building scalable applications that need to handle asynchronous processes efficiently.

<?php // Example of consuming messages from a RabbitMQ queue require_once __DIR__ . '/vendor/autoload.php'; use PhpAmqpLib\Connection\AMQPStreamConnection; use PhpAmqpLib\Message\AMQPMessage; // Create a connection to RabbitMQ $connection = new AMQPStreamConnection('localhost', 5672, 'user', 'password'); $channel = $connection->channel(); // Declare a queue to consume messages from $channel->queue_declare('task_queue', false, true, false, false, false, null); echo 'Waiting for messages. To exit press CTRL+C', PHP_EOL; // Callback function to process messages $callback = function ($msg) { echo 'Received ', $msg->body, PHP_EOL; // Simulate some processing time sleep(substr_count($msg->body, '.')); echo 'Done processing ', $msg->body, PHP_EOL; $msg->ack(); // Acknowledge the message }; // Set up a consumer on the task_queue $channel->basic_qos(null, 1, null); // Fair dispatch $channel->basic_consume('task_queue', '', false, false, false, false, $callback); while ($channel->is_consuming()) { $channel->wait(); // Wait for incoming messages } $channel->close(); $connection->close(); ?>
