[snip] Is there any way to use PHP to determine the zip code someone is visiting from, assuming they are all from the US? [/snip] You would have to determine their IP, which, some being dynamically assigned at log on, would not necessarily indicate the users location. Then you would have to be able to map the IP to a zip code. The short answer is no. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
