How can PHP sessions be effectively used to manage user permissions in a forum environment?

To manage user permissions in a forum environment using PHP sessions, you can assign different permission levels to users when they log in. These permission levels can be stored in the session variables and checked on each page to determine what actions a user can perform. By using session variables to store and manage user permissions, you can easily control access to certain features or content based on the user's role. 

// Start or resume a session
session_start();

// Set user permission level when user logs in
$_SESSION['user_permission'] = 'admin'; // example permission level

// Check user permission level on each page
if($_SESSION['user_permission'] == 'admin'){
    // Allow admin actions
} else {
    // Display message or redirect user
}
