php+webSoket implémente un exemple de code de salle de discussion (code source ci-joint)-tutoriel php-php.cn

本篇文章主要介绍了php+webSoket搭建chatServer示例（附源码）的资料,这里整理了详细的代码,有需要的小伙伴可以参考下。

最近在公司利用直播间搭建一个图文直播间时正好要用到chatsever，研究了一下html5的websocket 实现了双向通信，根据前人的经验折腾了几天弄了个聊天室，实现了发送图片，发送QQ表情，群聊私聊等功能，特地分享给各位新手参考学习，大牛可以忽略。
