What are the advantages of using a Message Queue system like RabbitMQ or Kafka in PHP for handling background tasks and maintaining task status?

When handling background tasks and maintaining task status in PHP, using a Message Queue system like RabbitMQ or Kafka can offer several advantages. These systems help decouple the processing of tasks from the application, ensuring reliable delivery of messages and enabling scalability by allowing multiple workers to process tasks concurrently. Additionally, they provide features like message persistence, message acknowledgment, and message routing, which can help in managing task status and ensuring fault tolerance. 

// Example PHP code snippet using RabbitMQ for handling background tasks

// Establish connection to RabbitMQ server
$connection = new AMQPStreamConnection('localhost', 5672, 'guest', 'guest');
$channel = $connection->channel();

// Declare a queue for background tasks
$channel->queue_declare('task_queue', false, true, false, false);

// Publish a message to the queue
$message = new AMQPMessage('Task data');
$channel->basic_publish($message, '', 'task_queue');

// Consume messages from the queue and process tasks
$callback = function ($message) {
    echo "Received task: ", $message->body, "\n";
    // Process the task here
    $message->delivery_info['channel']->basic_ack($message->delivery_info['delivery_tag']);
};
$channel->basic_qos(null, 1, null);
$channel->basic_consume('task_queue', '', false, false, false, false, $callback);

while (count($channel->callbacks)) {
    $channel->wait();
}

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