Question

我正在尝试在此基本登录页面中使用Session。我在哪里以及如何使用Session？谢谢。我看到了许多使用会话的示例，但请指出可以在何处添加会话。我是PHP编码的新手。

Answer 1

在您的loginn.php页面中。在页面顶部开始会话。像

session_start();//this

然后搜索输入Mobile_No并在数据库中输入密码（如果找到），然后分配会话变量user_id，如

$_SESSION['user_id'] = $user->ID;

注意：如果任何页面已经具有session_start();功能，则编写ob_start();功能。

如何在此代码中使用Session。无法理解
