So it would be eligible if filter_var() itself can intern e.g. via idn_to_ascii() convert a international Domain bevor check. This time it is only doable with a workaround - see Below "Test Script" Test script: --------------- function validate_email($mail) { if ( ! filter_var($mail, FILTER_VALIDATE_EMAIL) ) { $in = explode('@', $mail); $in[1] = idn_to_ascii($in[1]); return (bool) filter_var(join('@', $in), FILTER_VALIDATE_EMAIL); } return true; } $mail = "foo@müller.de"; var_dump( validate_email($mail) ); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65385&edit=1
