如何为已登录的用户禁用登录页面[关闭]

Question

How I can disable login page for users who logged in already? I tried a lot to writing php code for "if user logged in already can't logged in again and can't see login page" but I didn't know

<?php
    session_start(); 

    if(isset($_SESSION['user_name'])) 
    { 
        header('Location: home.php'); 
        exit;
    }
?>
