这篇文章主要给大家介绍了关于利用PHP+RabbitMQ实现消息队列的相关资料,文中通过示例代码介绍的非常详细,对大家学习或者使用PHP具有一定的参考学习价值,需要的朋友们下面来一起学习学习吧。
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

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)
