基于php在线学习平台管理系统
在线学习平台管理系统是基于php编程语言和mysql数据库开发,系统分为学员,教师,管理员三个角色,其中学员注册登陆后,可以查看课程,播放课程视频,在线考试,留言给教师等功能;教师登陆后可以管理课程,管理试卷和试题,对学生的留言查看等;管理员对学生,教师,试卷,课程,公告等进行管理。本设计功能齐全,界面简洁,适合作为php毕业设计参考和学习。
一.技术环境
php版本:5.3 及以上
后台框架:无,php原生开发简单易懂
开发工具: notepad++,sublime,phpstorm都可
数据库: mysql
服务器: apache
集成环境: phpstudy(或其他)
详细技术:HTML+CSS+JS+PHP+MYSQL+PhpStudy
