登錄php代碼保持清爽？

我和我的login.php頁面無法登錄的問題

，我不能工作了，爲什麼它不斷刷新頁面，每當我嘗試登錄。我正在使用我的index.php直接重定向到我的login.php不知道是否這是問題，因爲我改變它這是工作。有任何想法嗎？登錄php代碼保持清爽？

的index.php

<?php 
    header("Location: Login.php"); 
?>

的login.php

<?php 
ob_clean();session_start(); 

if (isset($_GET['logout'])){ 
    session_destroy(); 
} 

if (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true){ 
    header("Location: index.php"); 
} 

$Username = $_POST['username']; 
$EnteredPassword = $_POST['password']; 

if (isset($_POST['submit'])){ 
    if (is_dir("USERS/".$Username) === true){ 
     $myFile=fopen("USERS/".$Username."/Password.txt","r") or exit("Can't open file!"); 
     $CorrectPassword = fgets($myFile); 
     fclose($myFile); 

     if ($CorrectPassword == $EnteredPassword){ 
      $_SESSION['loggedin'] = true; 
      header("Location: Home.php");  
     } 

     else { 
      echo '<font color="#FF0000"><p align="center">Username or Password incorrect please try again</p></font>'; 
     } 
    } 

    else { 
     echo '<font color="#FF0000"><p align="center">Username or Password incorrect please try again</p></font>'; 
    } 
} 
?>

很顯然，如果你去index.php，你問的瀏覽器去login，不論是否用戶是否登錄：

<?php 
    header("Location: Login.php"); // This blindly redirects the user to the login page. 
?>

，而不是上面的代碼，檢查併發送用戶：

<?php 
    // Start the session. 
    session_start(); 
    // Instead check if the user is logged in and then redirect. 
    if (!isset($_SESSION['loggedin'])) 
     header("Location: Login.php"); 
?>

而且，不要忘了在開始與session_start()啓動會話。

在腳本開始時不需要'session_start（）'嗎？ –

@PraveenKumar感謝您的建議'＃same_name' ... :) –

@PraveenKumar權。我們提到我們，涉及'＃Mentionception' –
