PHP简单防盗链

?php $ADMIN[defaulturl] = "http://siyizhu.com/404.htm";//盗链返回的地址 $okaysites = array("http://siyizhu.com/","http://www.siyizhu.com"); //白名单 $ADMIN[url_1] = "http://siyizhu.com/temp/download/";//下载地点1 $ADMIN[url_2] = "";//下载

   


 
<?php

$ADMIN[defaulturl] = "http://siyizhu.com/404.htm";//盗链返回的地址
$okaysites = array("http://siyizhu.com/","http://www.siyizhu.com"); //白名单
$ADMIN[url_1] = "http://siyizhu.com/temp/download/";//下载地点1
$ADMIN[url_2] = "";//下载地点2,以此类推

$reffer = $HTTP_REFERER;
if($reffer) {
$yes = 0;
while(list($domain, $subarray) = each($okaysites)) {
if (ereg($subarray,"$reffer")) {
$yes = 1;
}
}
$theu = "url"."_"."$site";
if ($ADMIN[$theu] AND $yes == 1) {
header("Location: $ADMIN[$theu]/$file");
} else {
header("Location: $ADMIN[defaulturl]");
}
} else {
header("Location: $ADMIN[defaulturl]");
}

?>

使用方法:将上述代码保存为dao4.php,
比如我测试用的validatecode.rar在我的站点http://siyizhu.com/temp/download里面,
则用以下代码表示下载连接.
 
文件名?site=1&file=文件

例如以下URL.复制到你的站点下试试
 
http://722.512j.com/dao4.php?site=1&file=validatecode.rar

以上代码测试可用
