PHP重定向或cookie,不是在Godaddy上工作,而是在localhost上工作

So i've just uploaded my php to godaddy, except the redirects which were working have now stopped. There's supposed to be no difference between how code works on a live server to offline so i don't understand what's changed.

Here is a sample of the code which isn't working

The header link with the logout hyperlink which as far as i can tell acts as a hyperlink should

<div id="header">
           <div>
            <a href="index.php">Home</a> 
                <div id="loginreglink">
                <a href="Logout.php">Log Out</a>
                </div>
           </div>
          </div> 

The actual Logout page (logout.php)

<?php

require_once ('Connection.php');

header('Refresh: 0;');

            if (!isset($_COOKIE['Username'])){
                require ('LoginFunctions.inc.php');
                redirect_user();
            } else {
                setcookie('Username', '', time()-60*60*24*90, '/', '', 0, 0);
                require ('RedirectPage.php');
                redirect_user();
            }


?>

RedirectPage.php (the next page which should link to, immediately after access of the logout page)

<?php
            require ('index.php');
            redirect_user();
?>

Which then immediately links back to index, however the user should be logged out. This isn't happening.

What happens is the page redirects to index (as it should) presumably using the following sequence, which leads me to think that the redirects are working, but the user isn't logged out. The cookie isn't removed. I don't really understand why it isn't though because it does work through netbeans on localhost.

    It's easy. Unset the cookie.

    if (!isset($_COOKIE['Username'])){
       require ('LoginFunctions.inc.php');
       redirect_user();
    } else {
       setcookie('Username', '', time()-60*60*24*90, '/', '', 0, 0);
       require ('RedirectPage.php');
       //add this
       unset($_COOKIE['Username'];
       //or use setcookie and make the time to expire in the past and just put an empty value like
       $cookie_name = "Username";
       $cookie_value = "";
       $time = -3600;
       setcookie($cookie_name, $cookie_value, $time, "/");
       redirect_user();  
    }
