Are there alternative methods, aside from session expiration, that can be used to control user access and prevent unauthorized actions in PHP applications?

Session expiration is not the only method to control user access and prevent unauthorized actions in PHP applications. Another method is to implement role-based access control (RBAC), where each user is assigned a specific role (such as admin, moderator, user) with corresponding permissions. By checking the user's role and permissions before allowing certain actions, you can ensure that only authorized users can perform specific actions. 

// Example of role-based access control implementation
$userRole = getUserRole(); // Function to get the user's role

if($userRole == 'admin') {
    // Allow admin-specific actions
    echo "You have admin privileges.";
} else {
    // Deny access for non-admin users
    echo "You do not have permission to perform this action.";
}
