What are the potential risks of not immediately kicking out a banned user in a PHP session?

If a banned user is not immediately kicked out of a PHP session, they may still have access to restricted areas or functionalities on the website. This can lead to security breaches, unauthorized actions, or disruptions to the website's operations. To solve this issue, you can implement a check at the beginning of each page load to verify if the user is banned, and if so, immediately redirect them to a different page or log them out of the session. 

// Check if user is banned and kick them out if necessary
session_start();

if(isset($_SESSION['isBanned']) && $_SESSION['isBanned'] == true){
    // Redirect to a different page or log out the user
    header("Location: banned_page.php");
    exit();
}
