#47282 [NEW]: FILTER_VALIDATE_EMAIL is marking potentially valid emails as invalid

From: jachin at clockwork dot net Operating system: Gentoo PHP version: 5.2.8 PHP Bug Type: Filter related Bug description: FILTER_VALIDATE_EMAIL is marking potentially valid emails as invalid Description: ------------ I tried to refractor email validation code to use the FILTER_VALIDATE_EMAIL filter instead of a regex. Our Unit tests failed, because it marked the following email addresses as invalid: e.x.a.m.p.l.e.@example.com a@com Reproduce code: --------------- <?php $wacky_but_valid_emails[] = 'e.x.a.m.p.l.e.@example.com'; $wacky_but_valid_emails[] = 'a@com'; foreach( $wacky_but_valid_emails as $email ) { print "$email : "; $result = filter_var($email, FILTER_VALIDATE_EMAIL ); var_dump($result); } ?> Expected result: ---------------- e.x.a.m.p.l.e.@example.com : bool(false) a@com : bool(false) Actual result: -------------- e.x.a.m.p.l.e.@example.com : string(e.x.a.m.p.l.e.@example.com) a@com : string(a@com) -- Edit bug report at http://bugs.php.net/?id=47282&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47282&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47282&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47282&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47282&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47282&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47282&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47282&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47282&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47282&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47282&r=support Expected behavior: http://bugs.php.net/fix.php?id=47282&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47282&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47282&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47282&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47282&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47282&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47282&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47282&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47282&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47282&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47282&r=mysqlcfg
