Use PHP to try Rabbitmq (AMQP extensions) to send and receive messages

Consumer: Receiving Messages

Logic:
Create a connection--create a channel--> switch--Create a queue--bind switch/queue/route keys receive Message

" \ n "; Processing Messages $queue->ack ($envelope->getdeliverytag ()); Send ACK reply manually}

Producer: Send Message

Logic:
Create a connection--create a channel--> switch Object--Send a message

The areas to note are:

The queue object has two methods available for fetching messages: consume and get.
The former is blocked, no message will be suspended, suitable for use in the loop;

The latter is non-blocking, when the message is taken, and none returns false.

Test

Run the consumer:

Run producer, send message:

The consumer receives the message:
