Please reopen. dean@ernie:~$ php -r "var_dump(filter_var('fred@bücher.ch', FILTER_VALIDATE_EMAIL));" bool(false) Using: PHP 5.3.10-1ubuntu3.5 with Suhosin-Patch (cli) (built: Jan 18 2013 23:40:19) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2012 Zend Technologies Previous Comments: ------------------------------------------------------------------------ [2010-09-27 05:13:24] ahar...@php.net This has since been fixed, and works in the current 5.2 and 5.3 releases. ------------------------------------------------------------------------ [2006-11-11 11:19:54] christoph at ziegenberg dot de Description: ------------ The filter FILTER_VALIDATE_EMAIL does not accept IDN domain names, so valid email addresses are not accepted, the punycode version works. I know the check for this is a little bit complex, because the allowed chars in the domain name depend on the TLD. I think the current behavior is okay as default, but there should be an option to allow IDN domain names. Reproduce code: --------------- <?php var_dump(filter_var('test@tätärätää.de', FILTER_VALIDATE_EMAIL)); var_dump(filter_var('t...@xn--ttrt-loabbba.de', FILTER_VALIDATE_EMAIL)); ?> Expected result: ---------------- string(...) "..." string(...) "..." Actual result: -------------- bool(false) string(...)
