public.css:
/* 去掉网页空白 */ *{ margin: 0; padding: 0; } .container{ height: 100%; /* 创建一个表示多种颜色的渐变图片 */ background-image: linear-gradient(to right,#a3fbf9,#f89ed0); } /* 设置背景颜色 */ body{ text-align: center; } /* 设置字体大小 */ h1{ font-size: 45px; } a:link,a:visited{ color: rgba(230, 28, 139, 0.35); /* 去除超链接下划线 */ text-decoration: none; } a:hover{ color: cyan; /* 鼠标放置出现下划线 */ text-decoration: none; } /* 表单背景颜色 */ table{ background-color: white; margin-top: 50px; margin-left: 440px; width: 480px; height: 600px; border-radius: 20px; } .login input{ font-size: 20px; width: 200px; height: 40px; background-image: linear-gradient(to right,#a3fbf9,#f89ed0); color: #fff; border-radius: 20px; } input{ outline: none; width: 350px; border-bottom: 1px solid #dbdbdb; border-top: 0; border-left: 0; border-right: 0; } ::placeholder{ font-size: 14px; }四、用户中心页面
list.php:
<!DOCTYPE html> <!--声明为html-->
<html> <!--html标签-->
<head> <!--头部标签-->
<meta charset="utf-8"> <!--定义编码-->
<title>个人中心</title> <!--定义标题-->
<link rel="stylesheet" type="text/css" href="public.css"/> <!--调用css-->

$username = abc($_SESSION['username']); //接收用户名并用函数过滤，然后赋值给username
$sql = "select * from user where username = '$username'"; //在user表中查是否有此名称
$sqlzz = mysqli_query($conn,$sql); //执行数据库语法

//var_dump($aa); //看$aa类型
echo "<script>alert('修改成功');window.history.back(-1)</script>";
}
if(isset($_POST['outlog'])){ //接收退出登录
session_destroy(); //销毁session
header("location:login.php"); //重定向到login.php
}
}
?>
</head>
<body class="container"> <!--内容标签-->
<form action="list.php" method="post" autocomplete="on"> <!--form表单-->
<table> <!--定义表格-->
<tr>
<td class="login-wrapper">
<h1>个人中心</h1>
</td>
</tr>
<tr>
<td>
<label>

</tr>
<tr>
<td>
<scan id="post">
<input type="submit" name="outlog" value="退出登录"/>
</scan>
</td>
</tr>
</table>
</form>
</body>
</html>
五、数据库文件
database.php:
<?php $conn = mysqli_connect("localhost","root","root"); //打开数据库 $selet = mysqli_select_db($conn,"hacker"); //连接数据库 mysqli_query($conn,"set name 'utf-8'"); //设置表编码 ?>数据库可以调用database.php，也可以直接写入登录注册页
六、网页图标
ico.ico:
七、本数据库设置
数据库名称：hacker
数据库表名：user
八、效果图
