本篇文章给大家带来的内容是关于PHP和RabbitMQ实现消息队列的完整代码，有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
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)

//交换机
'exchange'=>'word',
//路由
