Answer
Use RabbitMQ, Kafka, Redis streams, or AWS SQS for async job processing and background tasks.
Quick Answer
Message queues decouple producers from consumers. In PHP: use RabbitMQ (via php-amqplib), Redis queues (Laravel Queue), or Beanstalkd. Producer pushes a job to the queue, consumer (worker) picks it up and processes. Workers run as long-running CLI scripts or via supervisor. Queues improve responsiveness (return immediately, process in background) and handle traffic spikes gracefully.
