$filename="play-js.php";//要解密的文件

//第一次base64解密后的内容中查找密钥

{
$decode_key=str_replace("),'","",$k[0]);
$decode_key=str_replace("',","",$decode_key);

//查找要截取字符串长度
$str_length="";
if(preg_match("/,\d*\),/",$content,$k))
{
$str_length=str_replace("),","",$k[0]);
$str_length=str_replace(",","",$str_length);
}
//截取文件加密后的密文
$Secret=substr($lines[2],$str_length);
//echo $Secret;

//直接还原密文输出
echo "";

function get_filetree($path){
$tree = array();
foreach(glob($path . '/*') as $single){
