 ?>@xuzuning 在http://bbs.csdn.net/topics/390303885给了一段解密的代码，需要如何运行？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;
}
 
echo unscrambler('需要还原的代码或文件名');
