脚本宝典收集整理的这篇文章主要介绍了PHP基于rabbitmq操作类的生产者和消费者功能示例，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

本文实例讲述了PHP基于rabbITmq操作类的生产者和消费者功能。分享给大家供大家参考，具体如下：

注意事项：

1、accept.PHP消费者代码需要在命令行执行

2、'username'=>'asDF','password'=>'123456' 改成自己的帐号和密码

RabbitMQCommand.PHP操作类代码

PHP;">
$host,'port'=>5672,'username'=>$username,'password'=>$password,'vhost'=>'/')
