Making a session expire and alert user

[AdRock]

I have a code snippet i've had for months but never used

 

I presume this goes at the top of every page like you would session_start() ?

 

When the session does expire, how do i alert the user they need to log back in again?

define('SESSION_TIMEOUT', 9000); //15 Mins

session_start();
$idletime = time() - isset($_SESSION['time']) ? $_SESSION['time'] : 0;

if($idletime > SESSION_TIMEOUT)
{
     //Reset session
     session_destroy();
     session_start();
}

$_SESSION['time'] = time();

Right after session_destroy. remove the session_start and put in your alert with a link to the login page. better would be to create an error then redirect to the login page and display the error just as you would for missing form data.

So where the session_start can i use a variable with the message and echo it out on the page where i want to display the error?
