I've tried searching the php manual and internet on how to delete cookies and I've tried it the exact same way they all say:

setcookie("name", '', 1);

or

setcookie("name", '', time()-3600);

But when I check the cookies in the cookies dialog in Firefox, it's still there with the same value. I set this cookie using the following line:

setcookie("name", $value, time() + 259200, $path);

I found this question on stackoverflow: http://stackoverflow.com/questions/2497501/cookie-wont-unset, but none of the answers solved the problem. I also tried putting all paramaters in, like the author said, but it had no effect.

Does anyone see the problem?
