As indeed FILTER_VALIDATE_EMAIL will allow with Rasmus' fix. It does however, according to the rules, differentiate between what is allowed between quotes and what is allowed without quotes. // $r = The new regexp used in PHP internally php > echo preg_match($r, '".tom."@ff.com'); 1 php > echo preg_match($r, '.tom.@ff.com'); 0 The fix is here: http://svn.php.net/viewvc/php/php-src/branches/PHP_5_2/ext/filter/logical_filters.c?r1=297350&r2=297349&pathrev=297350 > I can't see any reason that this would be different for web forms used > to collect email addresses (I'd just expect them to quote the > local-part if it doesn't match the 'atom' production) Indeed, but at the moment such quoting is not needed. The solution I proposed was thus a bit hasty to suggest, since it was too restrictive. The solution in the spec right now is however too permissive. -- Lars Gunther http://keryx.se/ http://twitter.com/itpastorn/ http://itpastorn.blogspot.com/
