你的问题在这里。检查您是否有这些文件夹。反正你的代码不好

  $dir = (mkdir(`folder/$new`));
   $d = new couty();
   $d->write(`$dir/$new.php`,$c);

我会做的几件事

  1. 将变量从 $d、$a、$c 重命名为有意义的名称 - > $new_directory、$output_filename 等
  2. 检查 $new 实际上是一个有效的名称。
  3. 检查 mkdir 是否成功创建目录。
  4. 为所有失败的情况添加错误处理。

将来可能发生或可能发生：

$dir = (mkdir(`folder/$new`));  <--- $new might be bad / folder might be bad / call might fail
$d->write(`$dir/$new.php`,$c);  <--- maybe the $dir/$new.php generated a bad path.

// future potential errors:
$new = trim($_POST[`coutyv`]); <---- new might not exist, might be invalid, contain invalid
