phpinclude questions? (performance & # of items)

[webwiz]

Ok I tried that but the pages come up blank without it...

So I tried this and it worked:

ob_start();
include("links.php");
$links = ob_get_contents();
ob_end_clean();

ob_start();
include("ad.php");
$adform = ob_get_contents();
ob_end_clean();
