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:
具体以官网为准

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' => [],
    ];
