You should be able to do that with just:

<meta http-equiv="refresh" content="10"/>

in the <head> section of your page (you can adjust the value of content 
from 5 to however many seconds you want between refreshes).

You could also look at adding some AJAX-yness to your page, and have it 
query your script for new output every 10 seconds, and then add that 
content to the existing page... it sounds like this behavior is what 
you're looking for, but it's slightly harder to pull off than the method 
mentioned above.
