估计是用什么混淆工具搞出来的吧，比如这个：http://segmentfault.com/q/1010000000095598

把代码格式化一下，大概可以变成这样子：

<code class="lang-php">global $ar;

$ar = array('眴暓簨亸悓' => __FILE__);

if(!defined('AAFEEBDEDCC')) {
    define("AAFEEBDEDCC", 1378718929);
    function f($a, $b="") {
        global $ar;
        $a = base64_decode($a);
        if(empty($a))
            return "";
        if($b == "") {
            return ~$a;
        } else {
            $c = $ar['2']($a);
            $b = $ar['3']($b, $c, $b);
            return $a^$b;
        }
    }
}

$ar['1'] = f('mpKPi4Y=', ''); // empty
$ar['2'] = f('jIuNk5qR', ''); // strlen
$ar['3'] = f('jIuNo肐+emw==', '');
echo $ar['3'];
$ar['睅斀垞Г潑'] = f('nZ6Mmsn↙oJuanJbmg==', '');
$ar['迁憛皶尰'] = f('HjgiKD繟/KiECKyQq', 'nJGOoMOQ');

我已经把变量名替换了，它加密的方法大概就是 base64 之后按位取反。

解密的方法很简单，就是跟着代码走，不断地加入 echo 语句，把中间的结果打印出来。

比如我在上面的代码中已经注释了，mpKPi4Y= -> empty 和 jIuNk5qR -> strlen 。我估计中间有一个地方会出现 eval 之类的东西，然后后面那个超大的字符串的就是用来 eval 的。

无奈的是上面的 ar['3'] 在我的 php 5.5.6 下运行不了。jIuNo肐+emw== 这个字符串本身也不是合法的 base64 串。如果这里不是编码问题的话，那估计是旧版本的 php 可以支持这个。楼主如果可以运行，可以沿着这个思路继续，就可以解密了。
