先培养对php的兴趣,就先了解php相对其他程序的优点.其实优点很多了.主要列举以下几点.
php能做任何事情,例如收集表单数据,生成动态网页,或者发送/接收 Cookies。但 PHP 的功能远不局限于此。
asp---------
1.微软平台,花钱买.
2.漏洞多.非开源,很多代码运行环境用法具体内容不公布.
3.效能差.服务器系统.
4.程式传写不结构化.
5.除错不容易.错误不好修改.
6.组件支持复杂多.
jsp---------
1.对硬件要求高.
2.要有java基础.
3.除错不容易.错误不好修改.
4.号称执行速度最快的.(通过编译加速,php也可以)
5.大型企业的商业模式较适合.(银行,企业.)
php---------
1.跨平台(microsoft,linux,unix)、跨web server(IIS,apache)
2.结构化(类似C)、除错容易.
3.效能机佳.
4.对硬体要求低.
5.源码公开、漏洞少、风险低.
6.支持的数据库广泛.
Adabas D InterBase PostgreSQL dBase FrontBase SQLite Empress mSQL Solid
FilePro(只读) Direct MS-SQL Sybase Hyperwave MySQL Velocis IBM DB2 ODBC Unix dbm
Informix Oracle(OCI7 和 OCI8) Ingres Ovrimos
其他:bbs、留言版、杂志、文章、架站机.甚至可以.....写命令列程式.写图形使用者界面.最重要不要钱。
php大概运行的环境:
服务器环境:apache+mysql+php+phpmyadmin 有个软件叫appserv.exe的集成这些.
使用的编写工具:Macromedia Dreamweaver 或 EmEditor等.
大概了解下php写的基本方式,PHP 的 echo() 语句显示了,大概4种写法:
最常见获取系统信息的
再写个自己初学测试的:
echo"买虚拟主机找坏狼!www.winshell.cn" //这里是php要写内容!
?>
基本先学这些了....主要的内容在以后呢....

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. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
