        );

        if(isset($_GET['logout'])) {
            $_SESSION['username'] = '';
            header('Location:  ' . $_SERVER['PHP_SELF']);
        }

        if(isset($_POST['username'])) {
            if($userinfo[$_POST['username']] == md5($_POST['password'])) {
                $_SESSION['username'] = $_POST['username'];
            }else {
                header("location:403.html"); //replace with 403
            }
        }
?>

System Login
                    
                    

                        
Username:
                        

                    
                    

                        
Password:
                        

                    
                    

                        
 
                        

                    
                
            
        
    

You will need a logout, something like this (logout.php):

// Below is not needed, unless header above is missing. In that case, put logged out text here.
