How to solve the problem with cookies in some browsers?

Question

PHP

There is a simple script.
Sets a cookie and redirects.

<?php
SetCookie('cp', 'd5dt4345', time()+(60*15), '/', $_SERVER['HTTP_HOST']);
header('Location: /administrator/');

For some reason, the solution works for me in all browsers, and refuses to work for the client in some browsers.
Watching HTTP logs
My
client
Where to dig?

Answer 1

Maybe the client has the wrong time? Or timezone?
Try to put more lifetime. Or compare the time yourself with the server using JS.
Or maybe you ran into a bug. There are several of them related to setting cookies and redirecting. Search on google

Answer 2

Perhaps the zones as mentioned above! Try to bypass it!

<?php
SetCookie('cp', 'd5dt4345', time()+(60*15), '/', $_SERVER['HTTP_HOST']);
$_COOKIE['cp'] = 'd5dt4345'; // он создаст куку на сессию, после перезатрется функцией SetCookie
header('Location: /administrator/');

Answer 3

Another option is to disable cookies in the browser.
