note 53567 added to function.preg-match

In regards to Stony666 email validator: Per RFC 1035, domain names must be combination of letter, numbers and hyphens. _ and % are not allowed. They should be no less the 2 and no greater then 63 characters. Hypens may not appear at begging or end. Per RFC 822, email address- when regarding username - % generally not accepted in "new" (ha 1982 'new') format. _ and - are OK (as well as "." but not in subdomain but rather "real" username) here's something a little better: if(preg_match('/^[A-Z0-9._-]+@[A-Z0-9.-]+\.[A-Z]{2,6}$/i', $data)) return true; Small problem with this thought, I can't wrap my mind around the limit domain name to 2-63 characters, nor how to check for hypens at begging and end. Maybe someone else can toss in a better revision? ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53567 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53567&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53567&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53567&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53567&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53567&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53567&report=yes Search -- http://master.php.net/manage/user-notes.php
