PHP+RabbitMQ实现消息队列(代码全篇)

摘要：前言先安装对应的这里用的是不同的扩展实现方式会有细微的差异扩展地址具体以官网为准介绍配置信息基类生产者类消费者类消费者可有多个配置交换机路由生产者路由只控制发送成功不接受消费者是否收到频道

前言

先安装PHP对应的RabbitMQ,这里用的是 php_amqp 不同的扩展实现方式会有细微的差异.
php扩展地址: http://pecl.php.net/package/amqp
具体以官网为准  http://www.rabbitmq.com/getstarted.html 

介绍

config.php 配置信息
BaseMQ.php MQ基类
ProductMQ.php 生产者类
ConsumerMQ.php 消费者类
Consumer2MQ.php 消费者2(可有多个)

config.php
