php socket 怎么中断

我有php建个socket循环监听端口
while(true){
recv.....
}
现在麻烦了，这个页面F5重运行没效果了，端口一直被监听
我改的代码效果出不来
得重启机器才行
哇，每次都得这样，这样调试太麻烦啦

回复讨论(解决方案)

那你不处理监听的内容吗？

那你不处理监听的内容吗？什么意思呀，处理啊
但是我改了while里的内容，客户端还返回的是原来的东西
关了网页(PHP),客户端还是那样返回
必须重启、接着重开服务端
就跟缓存了一样，不过我看了shell框，端口确实一直在listening
服务端该如何软重启呢，谢谢

既然你是处理客户端发来的数据的，那么你可以约定一个终止信号
当收到终止信号时就跳出循环并 socket_close 不就可以了吗

问题不清晰
理论上在while内捕捉一个条件，当满足是就break然后close就可以了
至于缓存问题这个比较怪，socket怎么会收到旧信息？
网页做这种内容时一般要设定即时过期(不缓存)以及自动刷新

你可以用 cli 模试调试呀

嗯，让客户端来发送终止消息，稍存一点安全问题，不过现在不用考虑啦，可以这样处理
To#4, 我说的缓存是比喻结果的现象，socket是带锁的，防重复启动；造成的原因就是socket启动后关不了，我不需要监听了也停不下来，没法调试服务端更新的内容；比方说，有人连上来了，发送个hello,我把hello改为hallo,不重启接收不到hallo,一直是hello

To#5,cli没听过哦，学习啦~
谢谢三位，结贴了
