Hello, I am well versed in coding with xhtml which requires all lower case and am pretty much a newbie at PHP so that is why I am asking this question. is this acceptible if ($_post [sender_email] == "") or does at have to be if ($_POST [sender_email] == "") in short, do uppercase and lowercase always have the same meaning. thx, -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
