WHOIS類的修改版_PHP教程

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  
function connect ($server) {
$this->RETRY=0;
while($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 ;  
$this->RETRY ;  
sleep 🎜>}  

// 取得簡單的查詢結果，並以行為單位，放入陣列
// 國際網域查詢
function rawlookup ($query, $server) {

if(!$query):  
return( "");  
endif;

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

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

if( $ptr):  
if(!ereg($query, "n$")):  
$query .= "n";  
endif;  
fputs($ptr, "$query" );  
$i=0;  
$this->FOUND=1;  
while(!feof($ptr)):  
$array[$i]=fgets($ptr)):  
$array[$i]=fgets($ptr,$ this->MAXLEN);  
$this->DATA_COUNT =strlen(chop($array[$i]));  
if(eregi( "No match for", $array[$i]) || eregi ("No entries found", $array[$i])):  
$this->FOUND=0;  
elseif(eregi( "WHOIS database is down",$array[$i]))) :  
$this->ERROR ;  
$this->FOUND=0;
