Hi , Just as David Hutto has said,What you need is the cronjob... Make a script say "check.php" which checks the db to see if any new entries are made... and if yes send the mail ... now using the cronjob feature in linux os(which will be provided as a service in your linux hosting cpanel), set a cronjob which calls the " http://www.yoursite.com/check.php"; URL every minute.... now a trigger will be there every minute to the script and the emails will be send irrespective of whether anyone is browsing the site or not.... hope it is clear...
