PHP+RabbitMQ Complete code for message queuing

Preface

Why use RabbitMq instead of ActiveMq or RocketMq?

First of all, I do not require 100% message acceptance from a business perspective, and I need to develop in conjunction with php, which has lower latency (subtlety level) than RocketMq. As for ActiveMq, it seems that there are many problems. RabbitMq has good support for various languages, so RabbitMq is chosen.

Install RabbitMQ corresponding to PHP first. Here, php_amqp is used. Different extension implementations will have slight differences.
