求urldecode解密方式，谢谢。

求高手知道一下代码的解密方式，用了黑刀及在线解密，一直未果，烦请赐教，谢谢。

回复讨论(解决方案)

真无聊，这种东西也要扰码

<?header("Content-type: text/html; charset=utf-8"); if(!file_exists('./data/install.lock')){    header("Location: /install/index.php");    exit;}define('APP_ROOT', str_replace('\\', '/', dirname(__FILE__)));/* 应用名称www.adminn.cn*/define('APP_NAME', 'app');/* 应用目录*/define('APP_PATH', './cmstao/');/* 数据目录*/define('PIN_DATA_PATH', './data/');/* 扩展目录*/define('EXTEND_PATH', APP_PATH . 'Extend/');/* 配置文件目录*/define('CONF_PATH', PIN_DATA_PATH . 'config/');/* 数据目录*/define('RUNTIME_PATH', './_runtime/');/* HTML静态文件目录*///define('HTML_PATH', PIN_DATA_PATH . 'html/');/* DEBUG开关*/define('APP_DEBUG', false);require("./core/ThinkPHP/ThinkPHP.php");?>

十分感谢X大帮助解密，可否告知解密的方式步奏，因为还有一些文件需要处理，不能总是劳烦大家，谢谢。

/** * 本函数可还原常见代码级扰码(微盾) **/function unscrambler($code) {  if(! is_array($code)) {    $code = str_replace('__FILE__', "'$code'", str_replace('eval', '$code=', file_get_contents($code)));    eval('?>' . $code);  }else {    extract($code);    $code = str_replace("eval", '$code=', $code);    eval($code);  }  if(strstr($code, 'eval')) return unscrambler(get_defined_vars());  else return $code;}//用法//echo unscrambler('待解码的文件名');

十分感谢X大的解答！
