好用的网站防镜像代码

if (document.location.host != "bt.myltd.ltd" && document.location.host != "bt.myltd.ltd" ) {
     alert('警告！检测到该网站为恶意镜像站点，将立即为您跳转到官方站点！');
     location.href = location.href.replace(document.location.host,'bt.myltd.ltd');
}

将上面代码中的域名改为你网站的首页主地址。

//防止恶意HTTP_USER_AGENT采集
$ua = $_SERVER['HTTP_USER_AGENT'];
$now_ua = array('FeedDemon ','BOT/0.1 (BOT for JCE)','CrawlDaddy ','Java','Feedly','UniversalFeedParser','ApacheBench','Swiftbot','ZmEu','Indy Library','oBot','jaunty','YandexBot','AhrefsBot','MJ12bot','WinHttp','EasouSpider','HttpClient','Microsoft URL Control','YYSpider','jaunty','Python-urllib','lightDeckReports Bot','PHP');
if(!$ua) {
header("Content-type: text/html; charset=utf-8");
    die('请勿采集本站，采集者木有小JJ！请正常访问！');
}else{
    foreach($now_ua as $value )
    if(eregi($value,$ua)) {
    header("Content-type: text/html; charset=utf-8");
    die('请勿采集本站，采集者木有小JJ！请正常访问！');
    }
}

放在入口文件开头即可，但采用这种方法可能会误杀RSS订阅，自己根据需要调整UA头。
