Bug #54403 [Com]: FILTER_VALIDATE_EMAIL

Edit report at http://bugs.php.net/bug.php?id=54403&edit=1 ID: 54403 Comment by: tomas dot brastavicius at quantum dot lt Reported by: mariomaresca at hotmail dot it Summary: FILTER_VALIDATE_EMAIL Status: Bogus Type: Bug Package: Filter related Operating System: windows 7 PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: Status of this issue should be changed to Feedback. We are discussing whether email address mail.@mail.com is valid as per RFC 2822, but the test script works as expected, i.e. filter_var('mail.@mail.com', FILTER_VALIDATE_EMAIL) returns false. I have checked this against 5.3.3 and the latest trunk, both on Linux. Perhaps this is Windows specific bug ? Previous Comments: ------------------------------------------------------------------------ [2011-03-30 15:29:14] carsten_sttgt at gmx dot de @aharvey > That's a valid e-mail address: RFC 2822 According to RFC 2822 and this topic FILTER_VALIDATE_EMAIL is working wrong ("mail.@mail.com" isn't a valid e-mail address, see the answer from Tomas). BTW: FILTER_VALIDATE_EMAIL is working according to RFC2822? In the manual I can't read which rules are used for validating e-mails. ------------------------------------------------------------------------ [2011-03-29 16:28:49] dtajchreber@php.net Once the expected/correct behavior is agreed upon, we should also add a test case for this. filter's behavior has been inconsistent across the last 10+ releases. ------------------------------------------------------------------------ [2011-03-29 15:18:29] tomas dot brastavicius at quantum dot lt It is not correct. Address contains no characters other than atext characters or "." surrounded by atext. dot-atom = [CFWS] dot-atom-text [CFWS] dot-atom-text = 1*atext *("." 1*atext) Reference, http://tools.ietf.org/html/rfc2822#section-3.2.4 ------------------------------------------------------------------------ [2011-03-29 11:41:10] aharvey@php.net That's a valid e-mail address: RFC 2822 only requires the local part to be a valid dot-atom, and dot-atom elements may end with a period. ------------------------------------------------------------------------ [2011-03-27 19:29:56] mariomaresca at hotmail dot it Description: ------------ --- From manual page: http://www.php.net/function.filter-var#Description --- filter_var with FILTER_VALIDATE_EMAIL takes as good this malformed email: "mail.@mail.com" Test script: --------------- $email='mail.@mail.com'; if (filter_var($email, FILTER_VALIDATE_EMAIL)) echo '$email is good'; else echo '$email is bad'; Expected result: ---------------- $email is bad Actual result: -------------- $email is good ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54403&edit=1
