任何mysql边的错误, connect失败, insert失败 都这样返回一坨数据
workerman进程告诉我:
WORKER EXIT UNEXPECTED


这样错误根本没法捕捉和提示用户 请教下这该怎么办?

看起来你使用的是workerman的webserver
数据库的这个异常不会导致进程退出,看起来是你并没有捕获这个异常,这个异常被workerman的webserver捕获了,并打印出来


WORKER EXIT UNEXPECTED一般是两个原因(抛异常不会导致进程退出)
1、代码中使用了exit die语句,如果是webserver开发,请使用Man\Common\Protocols\Http\jump_exit()代替
2、代码有致命错误,例如语法错误、调用了不存在的函数等等,这种错误在workerman/log下会有具体的错误日志


如果是web开发,也可以选择用传统的nginx/apache+PHP开发模式,这样能很好的结合现有的mvc框架(tp yii...)。而网页上的即时socket通讯(如websocket通讯)后台使用workerman来做
