基于php+mysql的期末作业小项目(学生信息管理系统)


前言

一个简单的php➕mysql项目学生信息管理系统,用于广大学子完成期末作业的参考,该系统实现增、删、改、查等基本功能。

1、登录界面

<!doctype html><html><head><meta charset="utf-8"><title>无标题文档</title><link rel="stylesheet" type="text/css" href="login.css" rel="external nofollow" ></head> <body><div class="login"><h2 class="BT">Login</h2><div class="zm"><form action="function.php?action=login" method="post">账号:<input type="number"  name="user">密码:<input type="password"  name="password"><p>没有账号?点击<a href="newuser.php" rel="external nofollow" >注册</a></p><div><input type="submit" value="登录"  class="dl"><input type="reset" value="重置" class="cz"></div></form></div></div></body></html>

当输入密码点击登录后会弹出“登录成功”或者“账号或密码有错误提示”
