这里我将在添加新用户时更新章节详细信息，使用mysql_insert_id()在php中获取此添加的用户ID，但我希望在ajax中访问此用户ID。由于我是网络新手，我不知道如何在ajax中获取php最后插入的用户ID并将其发送到数据字符串中。请问您可以帮我解决问题吗？
insert_search.php
<?php
include('header/page_header.php');
$user="root";
$server="localhost";
$password="";
$db="coedsproddb1";
$dbconn= mysql_connect($server,$user,$password);
mysql_select_db($db,$dbconn);

如果你想得到答案，那么尽量发布尽可能少的代码，因为没有人想要阅读一堆格式错误的行。 它不是关于ajax，更多的是关于获取数据的PHP 假设您正在使用MySQL，您可以在名为PHP文件的ajax中运行查询：
SELECT user_id FROM table_name
ORDER BY user_id DESC
LIMIT 1;
