Codeignitor saving unique page views

Question

What's the best way to count and them add to a total in my database the unique views of a page?

Answer 1

fields--    userid      page
data--      testuser    index.php/whatever/

Add userid and page in db.

If the testuser visits that page again, dont add. However if he visits a differnt page, add that info into db again.

Same with all users and pages.
