基于PHP的学生管理系统

前言

基于PHP的学生管理系统；

实现登录、注册、学生信息、修改学生、删除学生、查询学生、添加学生等功能；

环境准备

开发平台：PhpStrom2022.1.2 、Phpstudy_pro

数据库：MySQL5.7.26

技术架构

Bootstrap +PHP7.3.4+html5+css3

项目结构

页面展示

1.登录与注册页面

2.首页

3.学生信息

4.修改学生

5.查询学生

6.添加学生

7.管理员信息

8.修改管理员

9.添加管理员

10.查询管理员

11.数据库

注意

1.MySQL 版本5.0以上与8.0以上sql语句有差异，需要调整数据库语句

2.运行项目前提前配置好MySQL数据库

3.本系统实现功能仅供参考
