我有一个登录页面，允许用户在检查数据是否正确后输入电子邮件和密码，浏览器必须显示个人资料页面，但问题是在我输入电子邮件和密码后系统冻结并且即使数据也不会显示个人资料页面是真的。
但是，如果我回显一条消息，通知用户数据正确，浏览器会显示此消息，谁能帮助我？？？PLZ我从2天到现在都试过了，没有任何成功，没有人给我正确的解决方案。
我弄清楚错误是什么，但我不知道如何解决它
if($_SESSION['login'] != 'true'){
**header("location:index.php");**
}
//var_dump($login_user);
$login = ($_SESSION['login']);
$id = ($_SESSION['user_id']);
$login_user = ($_SESSION['username']);
$firstname = ($_SESSION['first_name']);
$lastname = ($_SESSION['last_name']);
请尝试我的代码，任何人都告诉我这是错误的
