1.簡化了程式碼。 （其實就是去掉了一些用不著的變數的定義）
以上就介紹了www.haoyisheng.com WHOIS類的修改版，包括了www.haoyisheng.com方面的內容，希望對PHP教程有興趣的朋友有所幫助。
2、針對從INTERNIC檢索到的信息過於簡單，根據INTERNIC反饋的信息中的WHOIS SERVER進行進一步查詢。例如，YAHOO在whois.networksolutions.com上有更詳細的資訊。
class whois {
var $use_cache = 1;
var $FROM_CACHE=0;
var $cache_dir = "./"; // 依照你的系統自行設定
var $cache_dir = "./"; // 依照你的系統自行設定
var $port = 43;
var $MAXLEN = 100;
// 若您想在連線失敗後自動重試，
// 設定重試次數$MAX_RETRIES
var $MAX_RETRIES = 0; >var $SLEEP_VAL = 1;
var $RETRY = 0;
var $FOUND = 0; // 查詢沒有結果，次值為0
var $ERROR = 0; // 查詢過程中的出錯次數
var $DATA_MIN = 8; // 我們至少應該取得8個位元組的資料
var $DATA_COUNT = 0;
var $WHOIS_SERVER;
var $NEW_WHOIS var $WHOIS_SERVER;
var $NEW_WHOIS;
var $WHOIS_SERVER;
var $NEW_WHOIS $FURTHER_INFO = 0;
// 開啟和WHOIS SERVER的SOCKET連線
// 預設的是whois.internic.net
function connect ($server) {
$this->RETRY=0->RETRY=0 ;
while($this->RETRY MAX_RETRIES):
$ptr = fsockopen($server, $this->port);
if($ptr>0):
$this->ERROR=0; // just in case we're on a retry
return($ptr);
else:
$this->ERROR++
sleep($this->SLEEP_VAL);
endif;
endwhile;
}
// 取得簡單的結果，並以簡單的資訊方式放入數組>// 國際網域查詢
function rawlookup ($query, $server) {
if(!$query):
return( "");

$ptr=$ this->connect($server);
