Hi.
At some point of my site, I need to update a cookie for a user but since updating a cookie is not an option, and what we really do is re declare it rather than updating, I need to keep the other values of it.
For example, some users will go with a cookie that's set to expire after closing the browser and some, in a few days.
So, basically my question is: how do I read other values of a cookie such as the expiry date...etc?

Thanks

what if you were to just set another cookie that stores their expiry time

You can read the expiry date of a cookie by checking the response headers. Here is an example:


<?php

setcookie("hello","bar",time()+3600);
echo '<pre>'; print_r($_COOKIE); echo '</pre>';
echo '<pre>'; print_r(getallheaders()); echo '</pre>';
echo '<pre>'; print_r(apache_response_headers()); echo '</pre>';
?>
<a href="#">reload</a>


Response:

Array
(
[hello] => bar
