PHP header('Location') redirect not working

Question

I am working on a login script for my website and I can't use header('Location: url'); I'm using a live server for my tests Here's my code

<?php

ob_start();
session_start();

if (isset($_SESSION['username'])) {
    header('Location: http://some-website.com/user/');
    exit();
}

...

?>

But Instead of redirecting me to the URL given above It just shows the blank page Looks like It's using exit() but not header() I'm pretty confused

好吧，看来您的条件没有得到验证，这就是为什么您得到空白页的原因，请尝试通过在if语句var_dump($_SESSION)之前添加$_SESSION全局变量是否包含$_SESSION['username'] ，然后检查是否“用户名”在其中。
