In PHP authentication systems, how do I consume message queues?

        channel();

        // Declare a queue to consume messages from
        $channel->queue_declare('task_queue', false, true, false, false, false, []);

        echo ' [*] Waiting for messages. To exit press CTRL+C', "\n";

        // Callback function to process messages
        $callback = function($msg) {
            echo ' [x] Received ', $msg->body, "\n";
            // Simulate processing time
            sleep(substr_count($msg->body, '.'));
            echo " [x] Done\n";
            $msg->ack();
        };

        // Start consuming messages
        $channel->basic_consume('task_queue', '', false, false, false, false, $callback);

        // Wait for incoming messages
        while ($channel->is_consuming()) {
            $channel->wait();
        }

        // Close the channel and connection (cleanup)
        $channel->close();
        $connection->close();
        ?>
