php检测域名是否被注册事例

以下为源码

以下为引用的内容：

if ($domain)

{

if ($domain)

{

// first get the domain server from internic

$fp = fsockopen( "rs.internic.net", 43, &$errno, &$errstr, 10);

if (!$fp)

{

echo "$errstr ($errno)

n";

}

else

{

fputs($fp, "$domainrn");

while(!feof($fp))

{

$buf = fgets($fp,128);

if (ereg( "Whois Server:", $buf))

{

$server = str_replace( "Whois Server: ", "", $buf);

$server = trim($server);

}

}

fclose($fp);

}

if ($server)

{

echo "很遗憾，$domain 在 $server 被注册:

下面是详细注册信息：
";

echo "

"; 

$fp = fsockopen($server, 43, &$errno, &$errstr, 10); 

if(!$fp) 

{ 

echo "Could not open connection to $server on port 43.n"; 

echo "$errstr ($errno)

n"; 

} 

else 

{ 

fputs($fp, "$domainrn"); 

while(!feof($fp)) 

{ 

echo fgets($fp,128); 

} 

fclose($fp); 

} 

} 

else { 

echo( "祝贺你！$domain 在 $now(time) 这个域名尚未注册。
"); 

} 

echo ( "

");

}

检索你要注册的域名，看是否被注册 yourname.com, .org, and .net domains

domain:www.
