Update a cookie value without changing its expiry date?
$c = $_COOKIE["count"];
$c++;
if (isset($_COOKIE["count"])) {
setcookie("count", $c);
}
else
{
setcookie("count", $c, time() + 86400, '/');
}

The only way you can update a cookie's value without updating its expiry date is by adding the expiry date itself into the value; that's because a browser only sends you the names and values of the cookies.
if (isset($_COOKIE['count'])) {
list($exp, $val) = explode('|', $_COOKIE['count'], 2);
++$val;
} else {
$exp = time() + 86400;
$val = 1;
}
setcookie('count', "$exp|$val", $exp, '/');

You can save expiry date in other cookie. When you update your cookie, just read expiry date from it and use it in your update.

You can't - PHP doen't know when the cookie will expire nor dose javascript (unless you copy the expiry time into the cookie contents).
