Bug #81332 [Nab]: urn: URIs are not validated properly

Edit report at https://bugs.php.net/bug.php?id=81332&edit=1 ID: 81332 User updated by: tamas dot nagy0404 at outlook dot com Reported by: tamas dot nagy0404 at outlook dot com Summary: urn: URIs are not validated properly Status: Not a bug Type: Bug Package: URL related Operating System: all PHP Version: Irrelevant Block user comment: N Private report: N New Comment: I think it is still a bug (or misdocumentation), you are referring to the http://www.faqs.org/rfcs/rfc2396.html in your manual for this function regardless what it is called which is about URIs, so it should either specify that only URLs are being validated or URIs too. Also... for example news:comp.infosystems.www.servers.unix` is not a URL either however it passes the validation regardless.

FILTER_VALIDATE_URL validates URLs, not URIs. ------------------------------------------------------------------------ [2021-08-05 07:00:28] tamas dot nagy0404 at outlook dot com Description: ------------ Hi, Looks like the filter_var('urn:isbn:0451450523', FILTER_VALIDATE_URL); function does not validate the urn: type of URIs properly. The "urn:" type of URIs are mentioned by http://www.faqs.org/rfcs/rfc2396.html however the function just marks as invalid whereas it should validate it according to http://www.faqs.org/rfcs/rfc2141.html that is referenced from the RFC2396.
