Complete code for implementing message queue with PHP and RabbitMQ

This article brings you the complete code for implementing message queues in PHP and RabbitMQ. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

First install the RabbitMQ corresponding to PHP. Here we use php_amqp. Different extension implementations will have subtle differences.
php extension address: http://pecl.php.net/package/amqp
For details, please refer to the official website http://www.rabbitmq.com/getstarted.html
