如何在php中获取cookie启动时间?

My problem is cookie has been set with expiry time and in value there is no start or expire time etc but I want to get its start time mean when this cookie created?

Basically when user enters into my site and browse through some pages and reach on a specific page where cookie created, now it continuous browsing and reach on some other page where I just want to check is this cookie created within 5 hours or within 1 day etc.

I want this because user may leave site during process completion and come again after some time then I will check if user came in specific time so I want to reopen same page where he left.

Sorry if my english is not good.

There is no option available to get Cookie Creation date/time. Whenever user visits your site, You can simply add a variable + value([creation_datetime=>2016-06-10 10:10 AM]) in the cookie, and retrieve it whenever you want it.

Here is example

Example 1

Example 2

You can add current time in cookie value and check anytime when it was created (until it expires)
