PHP+RabbitMQ實現(xiàn)消息隊列的完整代碼

 更新時間:2019年03月20日 15:10:36   作者:SokminYo  
這篇文章主要給大家介紹了關于利用PHP+RabbitMQ實現(xiàn)消息隊列的相關資料,文中通過示例代碼介紹的非常詳細,對大家學習或者使用PHP具有一定的參考學習價值,需要的朋友們下面來一起學習學習吧

前言

為什么使用RabbitMq而不是ActiveMq或者RocketMq?

首先,從業(yè)務上來講,我并不要求消息的100%接受率,并且,我需要結合php開發(fā),RabbitMq相較RocketMq,延遲較低(微妙級)。至于ActiveMq,貌似問題較多。RabbitMq對各種語言的支持較好,所以選擇RabbitMq。

先安裝PHP對應的RabbitMQ,這里用的是 php_amqp 不同的擴展實現(xiàn)方式會有細微的差異.

  • config.php 配置信息
  • BaseMQ.php MQ基類
  • ProductMQ.php 生產(chǎn)者類
  • ConsumerMQ.php 消費者類
  • Consumer2MQ.php 消費者2(可有多個)

config.php

 <?php
 return [
  //配置
  'host' => [
   'host' => '127.0.0.1',
   'port' => '5672',

  //路由
  'routes' => [],
 ];
