php查询whois信息的方法

本文实例讲述了php查询whois信息的方法。分享给大家供大家参考。具体如下：

这里使用php通过查询whois信息的网站列表进行查询

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  //  $servers = array(    "biz" => "whois.neulevel.biz",    "com" => "whois.internic.net",    "us" => "whois.nic.us",    "coop" => "whois.nic.coop",    "info" => "whois.nic.info",    "name" => "whois.nic.name",    "net" => "whois.internic.net",    "gov" => "whois.nic.gov",    "edu" => "whois.internic.net",    "mil" => "rs.internic.net",    "int" => "whois.iana.org",    "ac" => "whois.nic.ac",    "ae" => "whois.uaenic.ae",    "at" => "whois.ripe.net",    "au" => "whois.aunic.net",    "be" => "whois.dns.be",    "bg" => "whois.ripe.net",    "br" => "whois.registro.br",    "bz" => "whois.belizenic.bz",    "ca" => "whois.cira.ca",    "cc" => "whois.nic.cc",    "ch" => "whois.nic.ch",    "cl" => "whois.nic.cl",    "cn" => "whois.cnnic.net.cn",    "cz" => "whois.nic.cz",    "de" => "whois.nic.de",    "fr" => "whois.nic.fr",    "hu" => "whois.nic.hu",    "ie" => "whois.domainregistry.ie",    "il" => "whois.isoc.org.il",    "in" => "whois.ncst.ernet.in",    "ir" => "whois.nic.ir",    "mc" => "whois.ripe.net",    "to" => "whois.tonic.to",    "tv" => "whois.tv",    "ru" => "whois.ripn.net",    "org" => "whois.pir.org",    "aero" => "whois.information.aero",    "nl" => "whois.domain-registry.nl"  );  if (!isset($servers[$ext])){    die('Error: No matching nic server found!');  }  $nic_server = $servers[$ext];  $output = '';  // connect to whois server:  if ($conn = fsockopen ($nic_server, 43)) {    fputs($conn, $domain."/r/n");    while(!feof($conn)) {      $output .= fgets($conn,128);    }    fclose($conn);  }  else { die('Error: Could not connect to ' . $nic_server . '!'); }  return $output;}// Some example queries:print whois_query('jonasjohn.de');print whois_query('example.com');print whois_query('example.org');
