效果
命令如下：
php index.php 可以查看到上图
php index.php start 开启服务（Debug模式）
php index.php start -d 开启服务（Daemon模式）
php index.php status 查看服务状态
php index.php reload 服务热加载
php index.php stop 关闭服务
index.php 这是文件名称，大家叫什么都可以。
目录结构如下：
├─ controller
│ ├── ...
├─ client
│ ├─ websocket
│ ├── ...
│ ├─ tcp
│ ├── ...
├─ server
│ ├─ config
│ ├── config.php
│ ├─ core
│ ├── Common.php
│ ├── Core.php
│ ├── HandlerException.php
│ ├─ log -- 需要 读/写 权限
│ ├── ...
├─ index.php
目前就这几个文件，后期研究新的知识点会直接集成到这里面。
说说实现了什么：
1、启动了 WebSocket、HTTP、TCP、UDP 等服务。
2、WebSocket 例子，在 client/websocket 文件夹，实现了视频弹幕。
3、HTTP 例子，在浏览器直接访问：http://ip:port，逻辑代码在 controller 文件夹。
4、TCP 例子，在 client/tcp 文件夹。
5、UDP 例子，直接运行 netcat-u ip port 即可。
6、相关配置，在 server/config 文件夹。

放不全，就放一个主要的文件吧（Core.php）。
