這篇文章僅僅只實現一個 Redis 連接池,篇幅就太少了,順便將前幾篇整合一下。
Demo 中大概包含這些點:
實現 MySQL 連接池
實現 MySQL CURD 方法的定義
實現 Redis 連接池
實現 Redis 方法的定義
滿足 HTTP、TCP、WebSocket 調用
提供 Demo 供測試
調整 目錄結構
HTTP 調用:
實現 讀取 MySQL 中數據的 Demo
實現 讀取 Redis 中數據的 Demo
640?wx_fmt=png
TCP 調用:
實現 讀取 MySQL 中數據的 Demo
實現 讀取 Redis 中數據的 Demo
WebSocket 調用:
實現 每秒展示 API 調用量 Demo

還涉及到,OnMessage.php、OnTask.php 、OnWorkerStart.php 等,就不貼代碼了。
