Have an array, put the question numbers (or ids) you have viewed in the array. Keep the array in the session. Display last 4 questions using the last 4 indexes of the array.

[Shanti C]

Yes Nav...
I also did like that ,i got..
But i want it with out sessions...
If any thought ,Please Tel me...
Thank you...

Well, then you have to pass the array as a hidden form element. But if the user uses back button, then the chances of these values getting 'lost' is more.

I guess you could also do that in the database too. Have like an faq_activity table that updates every time a user views an faq and then you could just pull the 4 most recent for that user. You'd have to keep it cleaned up else it will get fairly large, but it could be as simple as a faq_activitypk, faqpk and userpk.

$query = "select distinct faqpk, userpk from faq_activity where userpk = " . $userpk . " order by faq_activitypk desc limit 4";

something like that.
