How can I expire a page when a user clicks the refresh or back button of a browser using PHP?

Or how can we prohibit going back to the previous page when a user clicks the back button of a browser using PHP?

Well you cannot prevent using the back button with PHP, you can with JavaScript but all the user has to do is disable JavaScript to get around it.

You can use an approach like this to determine if the user has refreshed the page, if they have then use session_destroy () to end their session and redirect them elsewhere.
