PHP中获取域名WHOIS实现代码

图片[1]-源码桌面PHP中获取域名WHOIS实现代码-源码桌面

调用不同的查询服务器,一般就是国家级的查询中心

对应的 域名后缀 -> whois 服务器 的映射关系大致如下:

'com'=>'whois.internic.net',

'net'=>'whois.internic.net',

'org'=>'whois.pir.org',

'asia'=>'whois.crsnic.net',

'cn'=>'whois.cnnic.net.cn',

'cc'=>'whois.nic.cc',

这种方法,虽然实现起来很简单,但是你首先得收集到一份完整的域名对应的查询中心信息。

我这里提供的查询代码就是基于这种模式,大家可以继续完善

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];
  // 域名后缀对应的解析中心,可以在维基百科查到 
  //
  // http://de.wikipedia.org/wiki/Whois
  //
  $servers = array(
    "biz" => "whois.neulevel.biz",
    "com" => "whois.internic.net",

    "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;
}
// 调用方式:
print whois_query('域名');
