使用PHP和MYSQL为每个用户创建唯一的页面
我启动了一个待办事项应用程序。我已经从创建了登录和注册，并创建了待办事项应用程序，但是我需要为每个用户创建一个唯一的待办事项列表，现在所有用户都会得到相同的待办事项列表。我创建了一个数据库，其中有两个表，一个用于待办事项缩放的“TODO”，另一个用于用户。有没有办法将这两个表链接在一起，以便每个用户都有自己的待办事项 这是我的index.php代码注册使用PHP和MYSQL为每个用户创建唯一的页面,php,mysql,Php,Mysql,我启动了一个待办事项应用程序。我已经从创建了登录和注册，并创建了待办事项应用程序，但是我需要为每个用户创建一个唯一的待办事项列表，现在所有用户都会得到相同的待办事项列表。我创建了一个数据库，其中有两个表，一个用于待办事项缩放的“TODO”，另一个用于用户。有没有办法将这两个表链接在一起，以便每个用户都有自己的待办事项 这是我的index.php代码注册 <?php // Include config file require 'config.php'; /
