编辑：我已经检查了所有的权限，他们所有定在755，这样不应该成为问题Php标题不能在服务器上工作？
我做了一个脚本，这是工作。但后来我把文件放在不同的文件夹，由于某种原因header();不再被
工作这是我的文件夹的样子：
你有index.php形式，看起来像这样：
<form action='../login.php' method="post">
Gebruikersnaam:<br>
<input type="text" name="username" placeholder="Je leerlingnummer" required/><br>
wachtwoord:<br>
<input type="password" name="password" placeholder="Je wachtwoord" required/><br>
<div class="g-recaptcha" data-sitekey="6LeLbhgUAAAAAKUTJmf9CeIB2JbgsG3C0ftJsJAp"></div>
<input type="submit" name="submit" class="groottext" value="inloggen" />
</form>
登录脚本之前工作，但因为我已经把文件放在一个特定的文件夹里面，它不会重定向它保持页面在login.php这看起来l IKE在此：
if ($rows['authlvl'] == '1') {
header('location: leerling/repairs.php'); //User1
session_register("username");
session_register("password");
} else
if ($rows['authlvl'] == '2') {
header('location: admin/lloverzicht.php'); //User2
session_register("username");
session_register("password");
} else
if ($rows['authlvl'] == '3') {
header('location: admin/overzicht.php'); //user 3
session_register("username");
session_register("password");
} else {
echo "not authorised";
}
?>
有在login.php一些其他的代码这是工作，因为我已经测试过它，只是不工作的事情就是重定向：
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
<?php include($_SERVER['DOCUMENT_ROOT'] . '/var/www/includes/dbconnect.php'); ?>
$tbl_name="users";
$username=$_POST['username'];
$password=$_POST['password'];
$username = stripslashes($username);
$password = stripslashes($password);
$password = md5($password);
$sql="SELECT * FROM $tbl_name WHERE username='$username' and password='$password'";
$result=mysqli_query($conn,$sql);
$rows = mysqli_fetch_assoc($result);
if ($rows['authlvl'] == '1') {
header('location: leerling/repairs.php'); //User1
session_start("username");
session_start("password");
}
else
if ($rows['authlvl'] == '2') {
header('location: admin/lloverzicht.php'); //User2
session_start("username");
session_start("password");
}
else
if ($rows['authlvl'] == '3') {
header('location: admin/overzicht.php'); //user 3
session_start("username");
session_start("password");
}
else
{
echo "je hebt geen toegang tot deze pagina";
}
?>

添加代码的顶部加上'ob_start（）;'或最终回声后加上'退出（）'重定向后 –
@MasivuyeCokile所以退出（）？ –
没有，头之后'（）' –
