Removing ‘page-bottom’ widgets using a function

Hi Guys,
I’m trying to use a function to remove the page-bottom widgets from a page.
I know there are other ways of doing this using css or removing the call get_sidebar(‘page-bottom’). But I guess this is mainly an exercise to get more of an understanding of WP.

I currently have this function, which is identical to another I have used to remove ‘thematic_sidebar’. I just can’t seem to target the ‘page-bottom’ widgets.

<?php
function remove_page_bottom() {
if (is_page()) {
return FALSE;
} else {
return TRUE;
}
}
add_filter(‘page-bottom’, ‘remove_page_bottom’);
?>

I’ve also tried using ‘widget_area_page_bottom’ but nothing so far has worked.

If anyone could advise, it would be greatly appreciated.

Thanks
