Bug #55008 [NEW]: PHP Filter email doesn't work for facebook emails

From: Operating system: x86_64 GNU/Linux PHP version: 5.3.6 Package: Filter related Bug Type: Bug Bug description:PHP Filter email doesn't work for facebook emails Description: ------------ Hello, it seems the filter function is not working the "new" facebook emails like: apps+xxxxxxxxxxxxxxx.xxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@proxymail.facebook.com where x is an alpha numeric character. It returns false. This new feature comes from 2010 January, see: http://www.allfacebook.com/facebook-developers-prepare-to-gain-access-to-user-emails-2010-01 We got a lot of validation failures, cause of this, from facebook connected users, when we trying to use filter_var on these emails. A bit strange, cause if I change the "apps+xxxxxxxxxxxxxxx" to "apps+xxxxxxxxxx", 5 letter shorted, it accepts. However this won't help us :) Test script: --------------- <?php var_dump(filter_var("apps+xxxxxxxxxxxxxxx.xxxxxxxxxxxxxxx.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@proxymail.facebook.com", FILTER_VALIDATE_EMAIL)); Expected result: ---------------- It should return the given email address. Actual result: -------------- Returns false. -- Edit bug report at http://bugs.php.net/bug.php?id=55008&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=55008&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=55008&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=55008&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=55008&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=55008&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=55008&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=55008&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=55008&r=needscript Try newer version: http://bugs.php.net/fix.php?id=55008&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=55008&r=support Expected behavior: http://bugs.php.net/fix.php?id=55008&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=55008&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=55008&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=55008&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=55008&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=55008&r=dst IIS Stability: http://bugs.php.net/fix.php?id=55008&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=55008&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=55008&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=55008&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=55008&r=mysqlcfg
