一个PHP Whois域名检查函数代码

  以前在做PHP主机域名程序时候用的一个Whois检查代码,用来确定所查询的域名是否被注册,函数囊括了大部分的域名后缀,将根据后缀的不同连接到不同的查询服务器,以前能用,时间关系,我现在暂时没有测试那些查询网址现在是否还能用,若不能用,就需要你自己找资料,看看现在的网址是什么。

  01

  02function whois_query($domain) {

  03 $domain = strtolower(trim($domain));

  04 $domain = preg_replace('/^http:\/\//i','',$domain);

  05 $domain = preg_replace('/^www\./i','',$domain);

  06 $domain = explode('/',$domain);

  07 $domain = trim($domain[0]);

  08 // 切割域名

  09 $_domain = explode('.',$domain);

  10 $lst = count($_domain)-1;

  11 $ext = $_domain[$lst];

  12 //定义不同域名后缀所需要连接的查询服务器地址

  13 $servers = array(

  14 "biz" => "whois.neulevel.biz",

  15 "com" => "whois.internic.net",

  53 );

  54 if (!isset($servers[$ext])){

  55 die('Error: 没有找到匹配的服务器!');

  56 }

  57 $nic_server = $servers[$ext];

  58 $output = '';

  59 //连接域名服务器:

  60 if ($conn = fsockopen ($nic_server, 43)) {

  61 fputs($conn, $domain."\r\n");

  62 while(!feof($conn)) {

  63 $output .= fgets($conn,128);

  64 }

  65 fclose($conn);

  66 }

  67 else { die('Error: 不能连接到: ' . $nic_server . '!'); }

  68 return $output;

  69}

  70?>

  函数调用后,将直接返回结果。
