Hi, I am trying to check if an email is an email or not, so I used this that I found on the internet: preg_match("/^([a-zA-Z0-9])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-]+)+/", $_POST['email']); BUT, it returns false with the email some.thing@xxxxxxxxxx And ok for something@xxxxxxxxxx What is the error here :) /Peter -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
