If you're on Unix then look into using cron. Type the following at the command prompt to get info on cron: man 5 crontab Cron tasks can be scheduled at most once per minute. And if you're using Windows then I believe the equivalent would be task scheduler, but I've no idea how you would go about using it. -- Richard Heyes HTML5 graphing: RGraph (www.rgraph.net - updated 6th June) PHP mail: RMail (www.phpguru.org/rmail) PHP datagrid: RGrid (www.phpguru.org/rgrid) PHP Template: RTemplate (www.phpguru.org/rtemplate) PHP SMTP: http://www.phpguru.org/smtp -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
