Swoole 整合成一個小框架
效果
php
命令以下：
php index.php 能夠查看到上圖
php index.php start 開啓服務（Debug模式）
php index.php start -d 開啓服務（Daemon模式）
php index.php status 查看服務狀態
php index.php reload 服務熱加載
php index.php stop 關閉服務
index.php 這是文件名稱，你們叫什麼均可以。
目錄結構以下：
├─ controller
│ ├── ...
├─ client
│ ├─ websocket
│ ├── ...
│ ├─ tcp
│ ├── ...
├─ server
│ ├─ config
│ ├── config.php
│ ├─ core
│ ├── Common.php
│ ├── Core.php
│ ├── HandlerException.php
│ ├─ log -- 須要 讀/寫 權限
│ ├── ...
├─ index.php
目前就這幾個文件，後期研究新的知識點會直接集成到這裏面。
說說實現了什麼：
一、啓動了 WebSocket、HTTP、TCP、UDP 等服務。
二、WebSocket 例子，在 client/websocket 文件夾，實現了視頻彈幕。
三、HTTP 例子，在瀏覽器直接訪問：http://ip:port，邏輯代碼在 controller 文件夾。
四、TCP 例子，在 client/tcp 文件夾。
五、UDP 例子，直接運行 netcat-u ip port 便可。
六、相關配置，在 server/config 文件夾。
代碼
放不全，就放一個主要的文件吧（Core.php）。
