PHP会话if！isset {} else die（）

Question

I originally had this code (without die) but it would allow the page to be viewed.

I tried to add the die function, however it is just showing the blank page.

<?php require('dbcon.php');?>
<?php session_start();
if (!isset($_SESSION['adminauth']))
{
    header('login.php');
    die();
};
?>

@Rizier123 right, but one comment - HTTP/1.1 requires an absolute URI as argument to » Location: including the scheme, hostname and absolute path, but some clients accept relative URIs.

<?php require('dbcon.php');?>
<?php
/* Redirect to a different page in the current directory that was requested */
if (!isset($_SESSION['adminauth'])) {
    $host  = $_SERVER['HTTP_HOST'];
    $uri   = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
    $extra = 'login.php';
    header("Location: http://$host$uri/$extra");
    die();
}
?>
