Cookies ohne Reload

[jenslm]

folgendes:

  
$usertype_array = array('test1', 'test2');  
$language_array = array('test3', 'test4');  
  
if (isset($_GET['usertype'] && $_GET['language']) && in_array($_GET['usertype'], $usertype_array) && in_array($_GET['language'], $language_array))  
{  
	Header("Location: http://".$rootfolder."/system");  
	setcookie('usertype', $_GET['usertype'], time()[phone]);  
	setcookie('language', $_GET['language'], time()[phone]);  
}  

Problem die Cookies werden nicht geschrieben?
Was mache ich falsch?
Lg, Jens
