站点在localhost上完美运行，但在服务器上运行不正常

Question

I have weird situation.

I'm using this piece of code to logout the user from the site:

case 'exit':
    setcookie("hash", "", time() - 3600, '/');
    header('Location: /main');
    exit();
    break;

Exactly the same code is used on localhost, only difference is that on the server it won't logout. Just goes to the /main page and that's it. User stays logged in, but it perfectly works on localhost.

Answer 1

I've had this problem aswell, I found out cookies and sessions are required by most webservices to be the VERY first line of the file. Remember that header() must be called before any actual output is sent.

More about headers: http://php.net/manual/en/function.header.php

Answer 2

You should give complete route on the server. //example header("Location: http://www.example.com/login ");
