一段防盜連的PHP代碼

$ADMIN[defaulturl] = http://www.163.com/404.htm; //盜鏈返回的地址
$okaysites = array("http://www.163.com/","http://163.com") ; //白名單
$ADMIN[url_1] = http://www.163.com/download/; //下載地點1
$ADMIN[url_2] = "";//下載地點2，以此類推

$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:將上述代碼儲存為dao4.php,
比如測試用的validatecode.rar在網站http://163.com/download裡面,
則用以下代碼錶示下載串連.

檔案名稱?site=1&file=檔案
