十、Swoole 基础学习笔记 - Swoole Server 监听多端口服务
hi，我是温新，一名PHPer
文章基于 Swoole 5.0.1 版本编写。
学习目标：了解 Swoole Server 多端口的使用及其使用场景
说明：本篇文章结合官方文档编写及参考网络资料编写，虽非全部原创，但也是结合了自己的理解，若转载请附带本文 URL，编写不易，持续编写更不易，谢谢！
为什么需要使用多端口
在实际环境中，可能一个服务可能需要提供不同的功能服务，如此，在一个服务中可以根据不同的端口提供不同的服务。Swoole 中 使用 listen 实现多端口的监听。

在这个案例中，监听了一个新的端口 9501，那么多端口连接时，信息是如何处理的？若没有对新绑定的端口进行绑定新的回调，那么会共享已给出的回调。下面给出两个客户端来验证：
