$con = mysqli_connect('localhost','root','123456','test');
mysqli_set_charset($con,'utf8');
if(!$con){
die('Could not connect:' . mysql_error($con));
}
$sql = "select * from login";
$result = mysqli_query($con,$sql);
$rows = array();

shanchu.php(单项删除也可以直接填adminDel.php的路径):

<?php
 
$aaa = $_GET ["sno"]; //删除方式使用的get,照旧
 
$db = new mysqli("localhost","root","123456","test");
 
$sql = "delete from login WHERE id='{$aaa}'";
 
if($db->query($sql)){
    //  header("location:list.php");
    echo "<script>alert('删除成功!');window.location.href='list.php'</script>" ;
}else{
    echo "删除失败";
}

?>

xiugai.php(修改页面):

<html xmlns="http://www.w3.org/1999/xhtml">
 
<head>
 
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
 
  <title>无标题文档</title>
 
</head>
<body>
<h1>修改</h1>
 

<?php
 
$sno = $_GET{"sno"};
 
$db = new mysqli("localhost","root","123456","test");
 
$sql = "select * from login WHERE id='{$sno}'";
 
$r = $db->query($sql);
 
$arr = $r->fetch_row();
 ?>

<form action="update.php" method="post">
<p>id:<input type="text" name="id" value="<?php echo $arr[0]; ?>"/></p>  
<p>用户名:<input type="text" name="username" value="<?php echo $arr[1]; ?>"/></p>  
<p>密码:<input type="text" name="password" value="<?php echo $arr[2]; ?>"/></p>  
<p>邮箱:<input type="text" name="email" value="<?php echo $arr[4]; ?>"/></p> 
</p>
  <p><input type="submit" value="修改完毕"/></p>
</form>

</body>
 
</html>

xiugai.php更新页面还可以这样写:

<?php
 
//创建连接:四个参数分别为 服务器地址、用户名、密码、数据库名
$conn = mysqli_connect("localhost","root","123456","test");
$sno = $_GET{"sno"}; 
//查询数据的sql语句
$sql = "select * from login WHERE id='{$sno}'";
 
//执行语句接收返回值
$result = mysqli_query($conn,$sql);
//输错查询的数据
while ($row = mysqli_fetch_array($result)){?>
<style type="text/css">
	.list{margin: 0 auto;}
	.list p{font-size: 1rem;padding: 5px 0;}
	.list p span{display: inline-block;width: 100px;}
	.list p input{padding: 5px 0;outline:none;border: 1px solid #ccc;border-radius: 4px;-webkit-box-shadow: inset 0 1px 1px rgba(0, 0, 0, .075);box-shadow: inset 0 1px 1px rgba(0, 0, 0, .075);-webkit-transition: border-color ease-in-out .15s, -webkit-box-shadow ease-in-out .15s;-o-transition: border-color ease-in-out .15s, box-shadow ease-in-out .15s;transition: border-color ease-in-out .15s, box-shadow ease-in-out .15s;}
	.list p input:focus {border-color: #66afe9;outline: 0;-webkit-box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);box-shadow: inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);}
	.list .up_btn input{padding: 5px 10px;font-size: 1rem;border: 1px solid #2285ed;background-color: #FFF;}
	.list .up_btn input:hover{background-color: #2285ed;color: #fff;}
	.tran-b{-webkit-transition: all ease-out .5s;-o-transition: all ease-out .5s;transition: all ease-out .5s;}
</style>
<form action="./update.php" method="post" class="list">
	<p><span style="color: #2285ed;">id:<input type="hidden" value="<?php echo $row['id'];?>" name="id" /><?php echo $row['id'];?></span></p>
	<p><span>用户名:</span><input type="text" name="username" value="<?php echo $row['username'];?>" /></p>
	<p><span>密码:</span><input type="text" name="password" value="<?php echo $row['password'];?>" /></p>
	<p><span>邮箱:</span><input type="text" name="email" value="<?php echo $row['email'];?>" /></p>
	</p>
	<p class="up_btn"><input type="submit" value="修改完毕" class="tran-b"/></p>
</form>
<?php }?>

update.php(更新页面) :

<?php
error_reporting(E_ALL ^ E_NOTICE);
$id = $_POST["id"];
$username = $_POST["username"];
$password = $_POST["password"];
$email = $_POST["email"];
 
$db = new mysqli("localhost","root","123456","test");
 
$sql = "update login set username='{$username}',password='{$password}',email='{$email}' WHERE id='{$id}'";

if($db->query($sql)){
    //  header("location:list.php");
    echo "<script>alert('修改成功!');window.location.href='list_pl.php'</script>" ;
}else{
    echo "修改失败";
}     

?>

adminDel.php(批量删除页面):

<?php  
error_reporting(E_ALL ^ E_NOTICE); 
    // header('content-type:text/html;charset=utf-8');
    // header('Content-type: application/json;charset=utf-8');
    $str=$_GET['str'];
    // echo $str;
    $link = mysqli_connect( 'localhost' , 'root' , '123456' , 'test' );
    // mysqli_query($link,'set names utf8');   
    $sql='delete from login where id in ('.$str.')';
    mysqli_query($link,$sql);
?>

遇到的问题:

ajax提交数据报错,我是在本地运行的,参考:https://ask.csdn.net/questions/325174把dataType:'json',改成dataType:'text',就可以运行了,或者把dataType:'json'删掉也行。
