这是今天研究的PHP加密，看看大家能破嘛？

你的代码缺少名为 compat.php 的文件

你的代码缺少名为 compat.php 的文件

这个解密很容易解的

eval($WSc("JG9hTmhDd2JYZXo9Ik9aR2dKRm92eVFkekltcEFQc0x3VFNDaEJ1a2xIak5lcWlEV3RLRWF4TWNucmZSYlVYVlluQ1VKaUFLdUdzWFFTZ2FrVGJxbVdleWpJdnRkUkRwVlpZTnp4SE1vd0ZMbFBoQkVPZnJjVE45bW9Sa3B5WUlHQ2ZBMW9maWRmMjl2YzJPS1NncjVvMmFoQ1VBMENlNW1vUmtZSFdiSm96Y0pIeUFnWHo1RFhVZHVFZDlkVlVkUVhSRktpMkNhRV..............这个部分你把eval($WSc换成base64_decode就能解出一部分了

运行在服务器端的东西，有必要加密代码么？

这个由于缺少文件eykj_cn.php，只能角到这地步了：
include("eykj_cn.php");
$client = new EYS_Client('http://api.eykj.cn/api.php');
$client->setCharset("utf-8");
eval($client->eys("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",base64_encode($_SERVER["SERVER_NAME"])));

其实这种加密解决方法很简单，用echo代替eval，你就能知道执行的是什么了。然后如果输出来发现还是用eval的，继续。就能发现最终语句是什么了。

楼主失算了，姿态高明

这种加密好象是越来越多了，
不断变形之中。学习中。
