Second: consumer)
(1) Producer (create a rabbit_publisher.php file)
Create a connection --> Create a channel --> Create a switch object --> send a message

In this chapter, we will use RabbitMQ to build an RPC system, a client, and an extensible RPC server

What messaging scenarios are supported by AMQP and RabbitMQ?
