rabbitmq (MQ) stands for Message Queue. Message Queue is an application-to-application communication method. Applications communicate by reading and writing messages to and from queues without requiring a dedicated connection to link them. Message passing refers to programs communicating with each other by sending data in messages, rather than by making direct calls to each other, which is typically used for techniques such as remote procedure calls. Queuing refers to applications communicating through queues. The use of queues removes the requirement that receiving and sending applications execute simultaneously. Among the more mature MQ products are IBM WEBSPHERE MQ and so on.

PHP integrates with RabbitMQ and Kafka and other message queue systems through dedicated libraries and extensions to realize message production and consumption. 1. Use the php-amqplib library or amqp extension to connect to RabbitMQ, declare queues and publish or consume messages; 2. Integrate PHP with Kafka through the php-rdkafka library, and configure producers or consumers to send or read messages; 3. When processing fails, make sure that messages are only confirmed after successful processing, and use dead letter queues, retry mechanisms and logging to avoid infinite loops; 4. In RabbitMQ, ack/nack can be used to control messages, and Kafka needs to manually submit offsets; 5. In terms of performance, it is recommended to use CLI scripts to run consumers.
