PHP通过查询whois信息的网站列表进行查询，感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编来看看吧。
经测试代码如下：

/**
 * 查询whois信息
 *
 * @param 
 * @arrange (编程之家) jb51.cc
 **/
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: 
    //

    //
    $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');
