How to run a script leaving screen output of previous script

Hi. I want to run a php script without leaving the php that calls that script. Let's say I have a script called mypage.php which displays html. There is a link to link.php, which makes some database maintenance and has no output. I want to be able to run link.php from mypage.php, but don't want to display anything new on screen. As it is, when link.php runs, it displays a blank screen. I guess I could insert a header to reload mypage.php, but I wonder if there is a way of not leaving mypage.php at all. Is this posible? Thanks, -Alex
