如何重定向到另一个页面

Question

I simply wrote few lines on the top of the page that if the session is not set then it should redirect to another page but it's not working it show the white screen and doesn't redirect to another page Here is the code.

session_start();
include('includedb2.php');
if(! isset($_SESSION['login_user']))
{
  return Redirect::to('front');
  exit;
}

I added it on the top of the page but it's not working

Answer 1

I find that isset isn't optimal when checking if a key in an array exists. Instead, why not use array_key_exists to check if login_user is in $_SESSION instead?

Additionally, your redirect syntax seems a little different from what I saw in Laravel's redirect documentation .
