What potential issue is the user facing with the current code for automatic logout in PHP?

The potential issue the user is facing with the current code for automatic logout in PHP is that the session timeout is not being reset with each user interaction, leading to premature logout. To solve this issue, the session timeout should be updated with each user action to extend the session duration. 

// Start the session
session_start();

// Set the session timeout to 30 minutes
$timeout = 1800; // 30 minutes in seconds

// Check if the session timeout is set
if (isset($_SESSION['timeout'])) {
    // Calculate the time elapsed since the last user action
    $elapsed_time = time() - $_SESSION['timeout'];
    // If the elapsed time is greater than the timeout, destroy the session and logout the user
    if ($elapsed_time > $timeout) {
        session_destroy();
        header("Location: logout.php");
        exit();
    }
}

// Update the session timeout with the current time
$_SESSION['timeout'] = time();
