Help with PHP code please

[Parker Clack]

I have set up a routine for one of my pages that looks like

$countviews=$DB_site->query_first('SELECT SUM(views) AS totalviews FROM table');
$totalviews=number_format($countviews[totalviews]);
$monthviews = ?

echo "<p>";
echo "Total Number of Views - $totalviews";
echo "Views over last 30 days per day - $monthviews";

table in the above is the name of the table. What I need to know is what to put in monthviews line so that I get a total number of daily views over the past 30 days.

Thanks,
Parker
