## Create the file del.php

<?php
include 'conn.php';
    $id = $_GET['id'];
    $query="delete from message where id=".$id;
    mysql_query($query);
?>
//引入conn文件，使用get方式獲取id，使用sql語句來刪除id
<?php
//頁面跳轉(zhuǎn)，實(shí)現(xiàn)方式為javascript 
$url = "list.php";
echo "<script>";
echo "window.location.href='$url'";
echo "</script>";
?> 
//使用js頁面跳轉(zhuǎn)回list查看文件的頁面

Key points of this chapter:

  1. Use the $_GET method to obtain the ID value passed by the address for operation.


  2. Briefly understand the jump of JS
