'Can we capture Logout timestamp if the user closes browser or shutdown in php?

If it possible what be the steps? If not what are the possible steps? In my overall project: I'm using session so that users session in that application is tracked if they logs out as followings

id|session|login_time_stamp|logout_time_stamp
---------------------------------------------
1 |xgy67sw|   date-time    | date-time

But if they Shutdown pc or closes browser, logout time stamp is null.

id|session|login_time_stamp|logout_time_stamp
---------------------------------------------
1 |xgy67sw|   date-time    | null

What I want is, if the users closes browser or PC how to grab their exiting timestamp?

What you want is not possible.

Solution 2:[2]

There is no reliable way to capture when a user logs out of a website. Sessions expire after a certain time period has elapsed, but there is no reliable way to know when a user actually closes their browser or shuts down their computer.
