how to hide GET variable from url

how to hide GET variable from url

i'v been stuck with this <a href="profile.php?u=<?php echo $uiname ?>"/> ,
i'm trying to hide the $_GET variable but no success. what i'm trying to
achieve is something like www.mywebsitename.com/profile/name or
www.mywebsite.com/name instead of
profile.php?u=name
is it possible to do so ?
