note 75674 added to function.preg-match

I'm not happy with any pattern of email address that I have seen. The fallowing address are wrong: email1..@myserver.com email1.-@myserver.com email1._@myserver.com email1@2sub.myserver.com email1@sub.sub.2sub.myserver.com So, this is my pattern: $pat = "/^[a-z]+[a-z0-9]*[\.|\-|_]?[a-z0-9]+ @([a-z]+[a-z0-9]*[\.|\-]?[a-z]+[a-z0-9]*[a-z0-9]+){1,4} \.[a-z]{2,4}$/"; Best Regards, Elier http://www.faqs.org/rfcs/rfc1035.html RFC 1035 - Domain names - implementation and specification ---- Server IP: 69.147.83.197 Probable Submitter: 200.55.181.37 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/75674 Del: integrated -- https://master.php.net/note/delete/75674/integrated Del: useless -- https://master.php.net/note/delete/75674/useless Del: bad code -- https://master.php.net/note/delete/75674/bad+code Del: spam -- https://master.php.net/note/delete/75674/spam Del: non-english -- https://master.php.net/note/delete/75674/non-english Del: in docs -- https://master.php.net/note/delete/75674/in+docs Del: other reasons-- https://master.php.net/note/delete/75674 Reject -- https://master.php.net/note/reject/75674 Search -- https://master.php.net/manage/user-notes.php
