It does not validate that it's an HTTP URL, or that the hostname contains .s. Thus, "http://wwwtestcom"; is a perfectly valid URL, as is "banana://in.syrup", and anything else that can be parsed as a URL according to the rules in the above RFC. If you need to check for a specific type of URL you'll need to implement your own validation function, or google for one - there's loads out there. -Stuart -- S tuart Dallas 3ft9 Ltd http://3ft9.com/ > > > I've not really read the spec, so excuse me if I'm very wrong, but wouldn't that make it more of a URI syntax validator instead of a URL syntax validator? Yes, but the referenced RFC is titled "Uniform Resource Identifiers (URI): Generic Syntax," so the only thing that's "wrong" is the FILTER_VALIDATE_URL constant. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
