3. // fix the domain name:
4. $domain = strtolower(trim($domain));
5. $domain = preg_replace('/^http:\/\//i', '', $domain);
6. $domain = preg_replace('/^www\./i', '', $domain);
7. $domain = explode('/', $domain);
8. $domain = trim($domain[0]);
10. // split the TLD from domain name
11. $_domain = explode('.', $domain);
12. $lst = count($_domain)-1;
13. $ext = $_domain[$lst];
15. // You find resources and lists
16. // like these on wikipedia:
17. //
18. // http://de.wikipedia.org/wiki/Whois
