How to session timeout if page refresh in php?

I am developing a exam application and I want that when user give exam than on that time no one can reload my page.

I want to destroy session if my page refresh. I started the session on each page and after relevant session variables are set, the session is destroyed each time the page is refreshed or when I browse the same URL on a different tab.

I was also stuck in same kind of problem.

Just declare a session variable $_SESSION['page_load_count'] = 0; while creating/setting session after authentication.

Then just check this variable on exam.php page load if the value is 0 then continue loading the page and at the end of script just do a $_SESSION['page_load_count']++; else if value of $_SESSION['page_load_count']>0 then show that the page has been refreshed.

You can use session_destroy() to destroy a session.

However the whole point of sessions is to persist data between page refreshes; if you want to destroy this data each refresh it would be easier not to use a session.

What are you storing in the session; this might make a solution to your problem clearer? I.e. what lines of your code use $_SESSION? Please post some. Maybe it's an external library that taps into the session?
