用PHP查询域名状态whois的类

复制代码 代码如下:
classSearchDomain
{
var$domain="";
functionSetDomain($udomain)
{
$this->domain=$udomain;
}
//
//获取whois并分析域名状态
//ok未被注册
//非空值过期时间
//空值未知
//
functionGetInfo()
{
/*
$dinfo=trim($this->GetWhois());
if($dinfo=="")return"";
if(eregi("nomatch",$dinfo))return"ok";
//return$rs;
*/
$wl="";
$w_server=$this->GetServer();
if($w_server=="")return"";
$fp=fsockopen($w_server,43,$errno,$errstr,30);
if(!$fp)
{
echo$errstr;
return"";
}
$out=$this->domain."rn";
$out.="Connection:Closernrn";
fputs($fp,$out);
while(!feof($fp))
{
$wl=fgets($fp,255);
if(eregi("nomatch",$wl))
{
fclose($fp);
return"ok";
}
if(eregi("ExpirationDate",$wl))
{
$lines=split(":",$wl);
$t=trim($lines[1]);

{

$t=$ts[2]."-".$this->MonthToNum($ts[1])."-".$ts[0];
}
fclose($fp);
return$t;
}
}
fclose($fp);

}
//
//获得域名的整个whois信息
//
