WHOIS类的修改版
日期：2013-02-21 浏览次数：20473 次
1、简化了代码。（其实就是去掉了一些用不着的变量的定义）
2、针对从INTERNIC检索到的信息过于简单，根据INTERNIC反馈的信息中的WHOIS SERVER进行进一步查询。比如，YAHOO在whois.networksolutions.com上有更详细的信息。
class whois {
var $use_cache = 1;
var $FROM_CACHE=0;
var $cache_dir = "./"; // 根据你的系统自己设置
var $port = 43;
var $MAXLEN = 100;
// 如果你想在连接失败后自动重试，
// 设置重试次数 $MAX_RETRIES
var $MAX_RETRIES = 0;
var $SLEEP_VAL = 1;
var $RETRY = 0;
var $FOUND = 0; // 查询没有结果，次值为0
var $ERROR = 0; // 查询过程中的出错次数
var $DATA_MIN = 8; // 我们至少应该获得8个字节的数据
var $DATA_COUNT = 0;
var $WHOIS_SERVER;
var $NEW_WHOIS;
var $FURTHER_INFO = 0;
// 打开和WHOIS SERVER的SOCKET连接
// 默认的是 whois.internic.net
function connect ($server) {
$this->RETRY=0;
while($this->RETRY <= $this->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++;
$this->RETRY++;
sleep($this->SLEEP_VAL);
endif;
endwhile;
}
// 获取简单的查询结果，并以行为单位，放入数组
// 国际域名查询
function rawlookup ($query, $server) {
if(!$query):
return( "");
endif;
$ptr=$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($ptr,$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++;
$this->FOUND=0;
elseif(eregi( "Please wait a while and try again",$array[$i])):
$this->ERROR++;
$this->FOUND=0;
break;
endif;
if(eregi("Whois Server:",$array[$i])):
$this->NEW_WHOIS=trim(substr(trim($array[$i]),(strlen(trim($array[$i]))-13)*(-1)));
$this->FURTHER_INFO=1;
endif;
$i++;
endwhile;
fclose($ptr);
if($this->DATA_COUNT>$this->DATA_MIN):
return($array);
else:
$this->ERROR++;
endif;
else:
$this->ERROR++;
endif;
}
// 国内域名查询
function cnrawlookup ($query, $server) {
if(!$query):
return( "");

$ptr=$this->connect($server);
if($ptr):
if(!ereg($query, "n$")):
$query .= "n";
