1 | # CourseSelectionSystem
2 | 基于PHP的网上选课系统
3 | 针对选课系统，我主要使用了phpmyadmin + Dreamweaver完成了大部分工作
4 |
5 | 这是php老师发布的要求：
6 |
7 | “
8 |
9 | 设计一个《基于PHP的网上选课系统》
10 | 采用PHP，MYSQL，HTML设计一个基于B／S模式的选课系统，该系统的主要功能如下：
11 |
12 | 1、系统针对不同的用户角色进行管理，至少有以下三种角色：学生、教师、管理员。并提供以下主要功能：学生信息管理、课程管理、教师管理、学生选课管理等。
13 | 2、数据库采用MYSQL，至少包括以下五张表：
14 | 学生信息表(学号、姓名、所在院系ID、专业、性别、班级、密码)；
15 | 课程信息（课程代码、课程名称、教师编号、已选人数、总人数、上课时间、地点、学分、讲授学时、实验学时）；
16 | 教师信息表（教师编号、姓名、性别、所属学院、个人简介、密码）；
17 | 学生选课管理（学号、姓名、所在学院、所在专业、班级、课程编码），
18 | 院系信息表（院系ID、院系名称、所在校区）。
19 | 3、教师登录后提供以下功能操作：发布课程，查询已发布课程，查询选课学生信息，修改密码。
20 | 4、学生登录后提供以下功能操作：查看可选课程，选择课程，查询已选课程，退选课程，修改密码。
21 | 5、管理员登录后提供以下功能操作：管理学生信息，管理教师信息，修改密码。
22 |
23 | ”

25 | 使用前先阅读使用指南会更方便您的使用，谢谢！
