Based on php online learning platform management system acquisition (php graduation design)

基于phpOnline learning platform management system

The online learning platform management system is based onphp编程语言和mysql数据库开发,The system is divided into students,教师,管理员三个角色,After the students register and log in,Courses can be viewed,Play the lesson video,在线考试,Message to teachers and other functions;Teachers can manage courses after logging in,Manage exam papers and questions,View messages from students, etc;管理员对学生,教师,试卷,课程,Manage announcements, etc.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.
