recentviews

I'm not sure if there is an explanation on SO for beginners, but if so, could you provide the links.

I am interested in creating a "recent viewed" function that shows what links they clicked on before. I'm not sure if this is the 'correct' way to do it, but this is what I have so far...

user clicks on a link(say ad.php?posting_id=12).
if the user doesn't click on the link, no cookie or session is stored for the link
if the user clicks on the link, it sets a cookie for $_cookie['ad.php?posting_id=22']
Each time the user clicks, more cookies are set
In the recent viewed function, it gets all the $_cookie variables and displays them.
if the user wants to clear the history, just destroy all the cookies

I'm not sure if this is the way to do it, but is the viable? If not, what are the steps to create a "recent viewed" function
