即使我刪除了空白區域，標題也不會重定向

我在代碼中包含一個標題（），但它不重定向。我知道在header（）發送之前不應該有任何空格，但它仍然不起作用。有人可以幫忙嗎？提前致謝。即使我刪除了空白區域，標題也不會重定向

<?php 
    session_start(); 
    if(isset($_SESSION["owner"])){ 
     header("Location:index.php"); 
     exit(); 
    } 
?> 
<?php 
require_once("includes/connection.php"); 
if(isset($_POST["username"]) && isset($_POST["password"])){ 
$owner = $_POST["username"]; 
$password = $_POST["password"]; 
$query = "SELECT id FROM users WHERE username = '$owner' AND password ='$password' LIMIT 1"; 
$sql = mysql_query($query,$connection); 
$existCount = mysql_num_rows($sql); 
     if($existCount == 1){ 
     while($row = mysql_fetch_array($sql)){ 
     $id = $row["id"]; 
     } 
     $_SESSION["id"] =$id; 
     $_SESSION["owner"] = $owner; 
     $_SESSION["password"] =$password; 
     header("Location:list.php"); 
     exit(); 
     }else{ 
     header("Location:login.php"); 
     exit(); 
     } 
} 
require_once("includes/header.php");?>

Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source.</p>

你確定'$ _SESSION ['owner']'被設置了嗎？嘗試將你的'if'語句改爲'if（true）{'來測試它;如果重定向 - 問題是會話變量未設置（或爲空）。 – newfurniturey 2012-07-29 01:35:24

請定義「不起作用」。和位置應該是一個完整的網址，而不僅僅是一個文件名 – 2012-07-29 01:55:01

如果設置了'$ _SESSION ['owner']''也許你在開始時用BOM保存你的文件？檢查你的編輯器的文檔，並確保你沒有。 – Galen 2012-07-29 02:07:59

你有PHP的關閉和開啓塊之間的換行符：

?> 
<?php

沒有必要爲這些標籤。刪除它們兩個。
