PHP development student management system to delete student information

Create

We made a delete link on the index.php page

Also used JS warning box to confirm deletion

Delete information

Link to the database and delete the related information passed from the delete page The ID information

The code is as follows

<?php
header("content-type:text/html;charset=utf8");
$id = $_GET['id'];
$conn=mysqli_connect("localhost","root","root","study");
mysqli_set_charset($conn,"utf8");
$sql = "delete from stu where id='$id'";
$rw = mysqli_query($conn,$sql);
if ($rw > 0){
    echo "<script>alter('删除成功');</script>";
}else{
    echo "<script>alter('删除失败');</script>";
}
header('Location: index.php');
?>

In this way, our deletion function is completed. We will simplify and integrate all our previous codes
