PHP+RabbitMQ实现消息队列的完整代码

前言

为什么使用RabbitMq而不是ActiveMq或者RocketMq?

首先,从业务上来讲,我并不要求消息的100%接受率,并且,我需要结合php开发,RabbitMq相较RocketMq,延迟较低(微妙级)。至于ActiveMq,貌似问题较多。RabbitMq对各种语言的支持较好,所以选择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://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

代码语言:javascript复制
 <?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' =  [],
 ];
