PHP程序百行代码快速构建简易聊天室
基本功能:能登陆,聊天,记录在线人数IP事件,能控制聊天的字体颜色,自动把转化聊天中网址为链接地址,能定制聊天室标题、广告信息等等。使用文本作为存储媒体,又兴趣可以参考代码,并且进行扩展。
其实PHP作为快速开发的脚本语言是很棒的!

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
