Hi hadi:
As http server is stateless, php can not know if a client has stop
requesting.
you should do your trick on the client side.
But if you insist doing this on the server, you may need to write a
daemon process or crontab job , here's the step
1. Everytime the client make a request, your php code write a timestamp
in a temp file.
2. Your daemon process should read this file and compare to the
timestamp by NOW, if it is larger than you expect ,then do the if
statement thing in the daemon process.

You will have to make the script 2 parts. One to reload and the other to
execute the else (exiting). You need to use ajax to call the php script
every
second (for the first part) and use the page's onunload method to execute
the second part (user exited):

I already tried your method with onunload, the problem with onunload when I
change the page the script getting execute.
I already have javascript to pull php script, just I need php script doing the
flowing; when javascript stop pulling php script. Block in if statement
