with "=xxx" to receive a full display for each record.

사람이 나는 이유를 알고 있습니까 :

$domains = array('google.com'); 
$internic = fsockopen('whois.internic.net', 43); 

if (is_resource($internic) === true) 
{ 
    foreach ($domains as $domain) 
    { 
     fwrite($internic, $domain . "\r\n"); 
     socket_set_timeout($internic, 30); 

     while (feof($internic) !== true) 
     { 
      ph()->Dump(fread($internic, 4096)); 
     } 
    } 

    fclose($internic); 
} 

놀랍게도,이 내가 가진 출력했다 이 이상한 반응을 보이고 있습니까?

Answer 1

정확히 일치하는 항목 앞에 등호를 추가하십시오. 그렇지 않으면 이 google.com으로으로 시작하는 항목이 표시됩니다. 페이지 중간에 약 http://allmybrain.com/2007/10/10/programming-a-client-for-the-whois-protocol/을 참조하십시오.

이 특정 서버에서는 사실이 아니지만 "="는 모든 일치에 대한 전체 레코드를 표시한다는 의미입니다 (다시 읽으면 정보 메시지에 표시됨). 대신 "domain google.com"과 같이 "domain"키워드를 사용하십시오.
