[PHP]도메인 남은 기간을 알려주는 PHP 프로그램 (CLASS)

웹에서 사용방법 : http://zzom.co.kr/whois.php?domain=zzom.co.kr
쉘에서 사용방법 : #>php -q whois.php zzom.co.kr

도메인 구매 홈페이지 가면 다 검색 할 수 있지만 자체적으로 활용이 필요하면 사용해볼만한 소스.
 
클래스 형식으로 만들었습니다.

if (!$domain)
{
   $domain = $argv[1];
}
$GetExpire = new GetExpireDate;
$GetExpire->GetInfo($domain);

이렇게 해주시면 사용 가능 합니다. 
필요하신분, 공부하면서 활용해 볼 수 있을 것 같네요.
