Cookie not setting

[squiblo]

I have a page called 'change_language.php' and all that is in the page is this....

 

$lang = $_GET['lang'];
setcookie('language',$lang,time()+86400);

if (isset($_COOKIE['language']))
header('location: http://localhost/');

 

the page does redirect suggesting that the cookie has been set because of the if statement, but when I get to the redirected page I test if the cookie has been set by putting...

 

echo $_COOKIE['language'];

 

and nothing is echoed suggesting the cookie has not been set.

It seems so simple (probably is) but I cant find what is wrong
