PHP实现RabbitMQ消息队列（消息队列RabbitMQ）

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://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

return [

//配置

'host' => [

'host' => '127.0.0.1',

'port' => '5672',

'login' => 'guest',

'password' => 'guest',

'vhost'=>'/',

],

//交换机

'exchange'=>'word',

//路由

'routes' => [],

];
