PHP实现查询未注册的域名,具体代码如下：

$url = "http://www.qiuyumi.com/dict2/?n1=&d1=1&n2=&d2=1&n3=&s=0&p=";

$num = 161604/200; #

#$num = 1;

for($i=1;$i<=$num ; $i++){

echo $url = "http://www.qiuyumi.com/dict2/?n1=&d1=1&n2=&d2=1&n3=&s=0&p=" . $i;

$str = file_get_contents($url);

preg_match_all("/<div class="domainname">(.*)</div>/i",$str,$arr);

foreach($arr[1] as $v){

$v = trim(strip_tags($v));

echo $xml = file_get_contents("http://panda.www.net.cn/cgi-bin/check.cgi?area_domain=".$v);

$arrXml = (array)simplexml_load_string($xml);

if($arrXml["original"] == "210 : Domain name is available"){

$f = fopen("ostm.net.txt","a+");

fwrite($f,$v . "rn");

fclose($f);

}

}

}
