实现也是很简单，通过抓取腾讯的域名状态判断接口,从而判断出域名是否报毒。

代码如下：

<?php
header("content-type:application/json; charset=utf-8");
function curl($durl){  
    $ch = curl_init();  
    curl_setopt($ch, CURLOPT_URL, $durl);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ;   
    curl_setopt($ch, CURLOPT_BINARYTRANSFER, true) ;  
    $data = curl_exec($ch);  
    curl_close($ch);  
    return $data;  
 }
$urls=$_REQUEST['url'];
$url=str_replace("http://","",$urls);
$url=str_replace("https://","",$url);
$url=str_replace("www.","",$url);
$axs=curl('http://cgi.connect.qq.com/qqconnectopen/get_urlinfoForQQ?xmlout=1&url=www.'.$url.'&md5sum&version=5587');
$urlpd=strpos($axs, "<result type=\"513\">") !== false ? '已报毒' : '未报毒';
$result .=json_encode(array('url'=>$urlx,'result'=>$urlpd),JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT);
if ($result == '') {
    exit ("{ \"text\": \"检测失败！\" }");
}else {
    exit ($result);
}
?>
