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)
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 = "./"; // 依照你的系統自己設定
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;
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 $FURTHER_INFO = 0;
// 開啟和WHOIS SERVER的SOCKET.
// 開啟和WHOIS SERVER的SOCKET.
//is .internic.net

// 取得簡單的查詢結果,並以行為單位,放入陣列
