tp5+workerman+gatewayworker实现每分钟将数据广播到群组客户端

1.安装

安装workerman

composer require topthink/think-worker

安装gatewayworker

composer require workerman/gateway-worker

安装mysql，查询数据库返回数据使用

composer require workerman/mysql

准备工作到此结束
下面开始代码
在app下新建gatewayapp文件夹
在gatewayapp文件夹下新建controller、run两个文件夹，建立配置文件const.php，启动文件start_for_win.bat
在controller文件夹下新建GwEvents.php
在run文件夹下新建start_businessworker.php、start_gateway.php、start_register.php
目录结构如下

业务文件GwEvents.php内容
