PHP实现RabbitMQ消息队列（转）

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)

config.php

<?php
return [
    //配置
    'host' => [
        'host' => '127.0.0.1',
        'port' => '5672',
        'login' => 'guest',
        'password' => 'guest',
        'vhost'=>'/',
    ],
    //交换机
    'exchange'=>'word',
    //路由
    'routes' => [],
];
