Why is my title ("Location: $ _SERVER ['HTTP_REFERER']"); PHP function not working?

It works when I enter

header("Location: http://www.google.com");

but it doesn’t work when I have

header("Location: $_SERVER['HTTP_REFERER']");

I want to redirect the page to any page from which it appeared.

Try it: :)

if (!empty($_SERVER['HTTP_REFERER']))
    header("Location: ".$_SERVER['HTTP_REFERER']);
else
   echo "No referrer.";

However, to determine which page the user came from, I would prefer to use a session variable that gets reset on each page:

session_start();
echo "Previous page:", $_SESSION['loc'];
$_SESSION['loc']=$_SERVER['PHP_SELF'];

ps: This only works for local pages, you cannot track other websites.
