[RESOLVED] Help with URL

[kpowning]

Ok i have people who are submitting their websites to my link exchange. What I need to do is somehow:

1) Remove the http://www. or http://
2) Remove the .com or .net or .whatever extension

So I have the raw domainname with no extension then check my database for just the raw domainname to see if anypart of this site has already been submitted.

Please help me im soo lost honestly.
thanks in advance. 🙂

Use parse_url() to isolate the hostname.

preg_match('@^(?:http://)?([^/]+)@i',"http://www.test.com/index.php", $matches);
$host = $matches[1];

preg_match('/[^.]+\.[^.]+$/', $host, $matches);
echo matches[0];

WORKS GREAT but thanks for the reply bretticus

I am sorry to inform you that it works quite badly if my ISP were to submit its web address for link exchange. www.starhub.net.sg becomes net.sg, not starhub.

Now, ".com" is not a "domain name extension", but rather is a top level domain. However, terminology aside, running your example (after fixing matches[0] to be $matches[0]) gives me "test.com", but you want "test", so clearly it does not work even with your test case.

I suggest using parse_url($url, PHP_URL_HOST) to get the domain name, and from there use regex to extract the part that you want, keeping in mind that some domain names have a country specific top level domain, and yet have a generic domain at the second level.
