Without the apostrophes should work fine (with them you're telling it  
to use a literal string):

setcookie($itemName, $like, $inTwoMonths);

If it's not working, I suggest adding some debugging code in:

setcookie($itemName, $like, $inTwoMonths);
echo "Attempted to set a cookie called $itemName containing $like";

Make sure there's no output being sent to the browser before your  
call to setcookie().
