Edit report at https://bugs.php.net/bug.php?id=65027&edit=1 ID: 65027 Updated by: cmb@php.net Reported by: info at iwebsoft dot de Summary: FILTER_VALIDATE_EMAIL does not accept IDN domain names Status: Duplicate Type: Feature/Change Request Package: Filter related Operating System: PHP 5.3.10-1ubuntu3.6 with Suhos PHP Version: 5.5.0RC3 Assigned To: cmb Block user comment: N Private report: N New Comment: > An easy workaround is to just call idn_to_ascii() on the address > you pass to the filter. FTR: while this may be sufficient as workaround for the validation, the result of filter_var() would not be the desired email address. Previous Comments: ------------------------------------------------------------------------ [2015-06-15 23:16:40] cmb@php.net Actually, this is not a bug, because the documentation[1] states: | In general, this validates e-mail addresses against the syntax | in RFC 822, [...] However, IDNs are not allowed by RFC 822. Therefore I'm switching to feature request, and marking this ticket as duplicate of request #39469.
