You can add more logic if you don't want ANY invlaid domains being returned, even when max node count is greater than 0.

But like PetePuma said, there is no catch all for this. Some of it is going to have to be implementation specific.

PetePuma posted : I can't think of a one-size-fits-all solution that doesn't incorporate a list of all possible TLDs and adjusts accordingly. And even then, it's probably not precise.

somewhere.co.uk..

Any idea of a work around?

jayco437 posted : Not quite the PHP expert myself, but wouldn't something like this work just fine: »us.php.net/function.parse-url

Edit: Nevermind, just saw the actual code sample that was posted, and it used parse_url. My bad. I was looking at the question and the replies using regex and I know Python and Ruby both have tools to manage urls and uris, figured PHP should have one too.

PetePuma posted : This might not work for .co.uk URLs, where you want the last *3* parts of the URL. The country domains are a tricky bunch, and are not consistent.

vollie posted : ok, so i was looking for a straight-out answer to your question, then figured it out myself, and figured i might as well post it...
So, without further ado:

(?:.+://)?(?:[^/]*\.)?([^/]+\.[^/]+)(?:/?.*)?
replaced by $1

will strip anything other then the bla.bla before the / in any url, reliable as hell.

Oh, since you're using php; don't forget the starting and ending thing so like:
preg_replace('@(?:.+://)?(?:[^/]*\.)?([^/]+\.[^/]+)(?:/?.*)?@', '$1', $url);

(PS. if you do happen to find some way to beat it, please inform me ;))

JAAulde posted : Ahh, I see. Very well then:

»codepad.org/UXGS161q

If both TLD and "top level host" are found, you should get them back. Otherwise you get an empty string.

Jafo232 posted : Actually your code is right, what I asked for is wrong. I need the domain name with the TLD, example:

http://www.dslreports.com/some/path/to/a/file.ext?name=value

To return just:

dslreports.com

Same with any URL:

http://somesubdomain.domain.com/path/to/somewhere

Code and output: »codepad.org/LSQ1VyyL

Edit: this could be done with a regex, but URLs can vary so widely that I'd rather take a few steps and use built in functions where possible. I think this is more reliable in this case.

I tried that code and the output was:

"com"

Which would be the TLD

Jafo232 posted : Regex has never been my expertise, so I am going to ask here. :)

I have a form where a URL is being submitted. My task is to parse the URL and get just the top level domain (i.e. dslreports.com) and save that value. I cannot seem to find any decent existing code that does this in a bullet proof way. Anyone have any ideas?
