　　9. 使用PHP做Whois检查

　　function whois_query($domain) {

　　// fix the domain name:

　　$domain = strtolower(trim($domain));

　　$domain = preg_replace('/^http:\/\//i', '', $domain);

　　$domain = preg_replace('/^www\./i', '', $domain);

　　$domain = explode('/', $domain);

　　$domain = trim($domain[0]);

　　// split the TLD from domain name

　　$_domain = explode('.', $domain);

　　$lst = count($_domain)-1;

　　$ext = $_domain[$lst];

　　// You find resources and lists

　　// like these on wikipedia:

　　//

　　// http://de.wikipedia.org/wiki/Whois

　　//

　　$servers = array(

　　"biz" => "whois.neulevel.biz",

　　"com" => "whois.internic.net",
