ID: 54629 Updated by: dtajchre...@php.net Reported by: xmilky+php at gmail dot com Summary: FILTER_VALIDATE_URL rejects IPv6 URLs http://[::1]/ Status: Open -Type: Bug +Type: Feature/Change Request Package: URL related Operating System: amd64 GNU/Linux 2.6.35 PHP Version: 5.3.6 Block user comment: N Private report: N New Comment: "Validates value as URL (according to » http://www.faqs.org/rfcs/rfc2396), optionally with required components. Note that the function will only find ASCII URLs to be valid; internationalized domain names (containing non-ASCII characters) will fail." RFC 2396 doesn't support IPv6 addresses... would need to implement RFC 2732 checks... flipping to feature request.

For example this returns `false` even though it's a valid HTTP url: filter_var("http://[::1]:2000/push/thingy";, FILTER_VALIDATE_URL); I'm somewhat certain that FILTER_VALIDATE_URL actually used [`parse_url`](http://php.net/parse_url) behind the scenes to probe for URL correctness. But parse_url itself works perfectly fine on such addresses: Array( [scheme] => http [host] => [::1] [port] => 2000 [path] => /push/thingy So there is some limitation in the filter_var wrapper for _VALIDATE_URL. --- Note that this is a distinct issue to http://bugs.php.net/bug.php?id=48762&edit=2 which was about FILTER_VALIDATE_IP addresses only. Test script: --------------- <?php var_dump(filter_var("http://[::1]/path?qs";, FILTER_VALIDATE_URL)); ?> Expected result: ---------------- string(20) "http://[::1]/path?qs"; Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54629&edit=1
