Session cookie not deleting

Question

I'm using cookies on my site without expiration dates defined so they expire on the browser close but I'm having issues unsetting them. I'm using the following code to unset them but it's not correctly doing it. I should also add that I want it to remove it from all pages on the site. Any help would be greatly appreciated, thanks.

Code used to unset cookie

if (isset($_POST['logout'])) {
    unset($_COOKIE['dash']);
}

Cookie is being set like this:

setcookie("dash", $row['ID'], time() + (10 * 365 * 24 * 60 * 60), '/');

I tried what you said and it gives me the following error `Cannot modify header information - headers already sent` — Joe Scotto, Feb 25 '15 at 03:05
@Dagon What does it mean exactly by that error? I've been wondering this for a long time and have never really found an answer. — Joe Scotto, Feb 25 '15 at 03:07

@CommuSoft Yes that was my intention for it to never expire, well almost never. — Joe Scotto, Feb 25 '15 at 05:06

I had to move the function to the top of the page before any output was sent, this fixed it.
