关键代码长这样：
echo $Kyddly." ".$ltJjKV." ".$sCFCgN." ".$dhGfsR." ".$Kyddly."<br /> ";
刷新网页得结果：
即 .$Kyddly是base64_decode。
果断把eval后面的$Kyddly替换成base64_decode，
运行，正常，发现猜测没错：
eval函数改成echo:

猜测$ijsHOv还是base64_decode你就错了，base64_decode得到乱码，我就不掩饰不拐弯墨迹了，直接来干活！
他后面还有一段eval('?>'.$Kyddly($ltJjKV($sCFCgN($ijsHOv,$dhGfsR*2),$sCFCgN($ijsHOv,$dhGfsR,$dhGfsR),$sCFCgN($ijsHOv,0,$dhGfsR)))，去掉eval,设$text = $ijsHOv,把这些函数用上面输出的名称替换后得：
base64_decode(strtr(substr($text,52*2),substr($text,52,52),substr($text,0,52)))
写点代码：
$pattern = '/="([^"]+)"/';
preg_match_all($pattern, $decodestr1, $matches);
$text = implode('', $matches);
echo $text;
echo "<br /> ";
$decodestr2 = strtr(substr($text,52*2),substr($text,52,52),substr($text,0,52));
//运行看看
echo $decodestr2;
echo "<br />再 base64_decode看看<br />";
echo base64_decode($decodestr2);
一开始用骨锅，看了好久看不出啥，这里得用360浏览器看看。

刚好需要，已经下载了
你这灌水灌的毫无边际，我要是管理员非ban了你这种不可。 建议使用 `var_dump` 而非 `echo` 来输出，更适合通过浏览器预览的情况（不需要查看源码、开发者工具）。 这样的是什么加密的，可以破解吗？
goto Kh9eWjgxa;
$Kh9tIMC=I('grade_a');$map['c.grade_a']=$Kh9tIMC;goto Kh9xb;
谢谢 楼主加密网站是啥呀 所以，很多用php的转go了，就是不想折腾这个 插眼学习学习 想要楼主的加密网站，试着把自己的php加密一下看看:lol 要提升我自己了 php好像也有很多类型的加密的
