Its not echoing the COOKIE instead shows an error.

Error:Undefined index: pref[fontSize]

setcookie('pref[fontSize]',25);
setcookie('pref[favCategory]','news');
setcookie('pref[screenWidth]',1024);

echo $_COOKIE['pref[fontSize]'];

@BeatAlex array(2) { ["pref"]=> array(3) { ["fontSize"]=> string(2) "25" ["favCategory"]=> string(4) "news" ["screenWidth"]=> string(2) "25" } ["PHPSESSID"]=> string(26) "5mr3d4tt3uab6kdkal0blt1qt2" } — CoDINGinDARK

OK so it is setting then! Like the others have said you need to wait until the next request :) — Albzi

The documentation for setCookie, suggests that $_COOKIE will not hold vals from setCookie, till after the cookie has been set client side (e.g. next request, because the user might have their browser configured to not save cookies).
