Is it possible to read cookie expiration time with php ?
When I print_r($_COOKIE)
it outputs:
Array
(
[PHPSESSID] => 0afef6bac83a7db8abd9f87b
Or you can use the function time() on the value of the cookie, that way you need only one cookie and can retrieve data. The php code would look like this:
setCookie('cookiename', time(), time() + 86400);
That way, you'll have the cookie expiring in one day, and by retrieving it's value you can discover when it'll expire with something like this:
86400 - (time() - $_COOKIE['cookiename']);
no, there is no way.
Browser uses cookie parameters (path, expiration etc) only to determine to send a cookie or not, but none of these parameters being sent back to server.
don't think of a cookie as of a $_SESSON array member but as an HTTP header. That's always helps.
Only name and value are sent to the server so no other cookie data is available.
You can simply re-set the cookie if you want to extend its duration - that's just a few bytes more in the response so it doesn't matter at all.
