When you say machine, do you mean the client that you're sitting at, or the machine that hosts the data? As for doing it thru a web server, the amount of time Apache, et al, would consume is miniscule. The web interface would not be involved in the reading of the data or the processing, just the output-ing of the results. :) -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
