Php简介：

引用:PHP即“超文本预处理器”，是在服务器端执行的脚本语言，尤其适用于Web开发并可嵌入HTML中。PHP语法学习了C语言，吸纳Java和Perl多个语言的特色发展出自己的特色语法，并根据它们的长项持续改进提升自己，例如java的面向对象编程，该语言当初创建的主要目标是让开发人员快速编写出优质的web网站。 PHP同时支持面向对象和面向过程的开发，使用上非常灵活。

经过二十多年的发展，随着php-cli相关组件的快速发展和完善，PHP已经可以应用在 TCP/UDP服务、高性能Web、WebSocket服务、物联网、实时通讯、游戏、微服务等非 Web 领域的系统研发。

我们开发php网站需要配置apache、mysql,利用集成环境开发网站，例如小皮面板、xampp等集成环境,现在我们利用PHP来做一个登录功能
