與setCookie方法

Question

問題我認爲我正確地這樣做，但它沒有得到存儲的cookie信息

的login.php

session_start(); 
     $_SESSION['username'] = $user; 
     $_SESSION['password'] = $pass; 
      if(isset($_POST['remmemberme'])) 
    { ob_start(); 
     setcookie("kitbusername", $_SESSION['username'], time()+60*60*24*100); 
     setcookie("kitbpassword", $_SESSION['password'], time()+60*60*24*100); 
     echo '<script> 
     window.top.location.href = "index.php"; 
     </script>'; 
    } 

的index.php

<p class="welcome">Hello 
     <?php 
session_start(); 
if($_COOKIE['kitbusername']){echo $_SESSION['username'];} 
       elseif($_SESSION['username']){ 
         echo $_COOKIE['kitbusername']; 
       } else{ 
        echo 'Guest'; 
            }?> 
</p> 

的header.php

<?php session_start(); 
if(isset($_SESSION['username']) || isset($_COOKIE['kitbusername'])){ 
//Log Out Button// ?> 

sessi在啓動設置在

你們沒有的index.php使用session_start()所有頁面

調用ob_start()你叫ob_end_clean()，ob_end_flush()，ob_clean()，或ob_flush()後？
