Description:
------------
I was attempting to set a cookie using a boolean. TRUE works correctly as 1 but setting it FALSE would not save a cookie at all.

Reproduce code:
---------------
setcookie("name",FALSE,time()+60*60);

if you print_r($_COOKIE); it won't display name as being in the $_COOKIE array but if you

setcookie("name",TRUE,time()+60*60);

it lists name == 1 in $_COOKIE





Expected result:
----------------
If it's a by design issue it might be a good idea to include this in the docs stating not to use booleans with cookies.
