本文实例讲述了PHP实现websocket通信的方法。分享给大家供大家参考,具体如下:
执行方法:
首先先修改server.php与index.html的ip
通过命令行执行 [php路径]\php.exe "[文件路径]\server.php"
然后通过浏览器打开index.html
server.php
<"htmlcode"><!doctype html> <html> <head> <meta charset="utf-8"> <title>websocket_TEST</title> </head> <body> <textarea class="log" style="width: 100%; height: 500px;"> =======websocket====== </textarea> <input type="button" value="连接" onClick="link()"> <input type="button" value="断开" onClick="dis()"> <input type="text" id="text"> <input type="button" value="发送" onClick="send()"> <script src="/UploadFiles/2021-04-02/jquery.min.js">websocket.class.php

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
