我有一个脚本：
- 浏览我的"./sample/"目录中的每个文件夹和子文件夹
- 打开每个.docx文件
- 用$_POST['PROPERTY']变量替换诸如"###PROPERTY##"之类的字符串
- 压缩文件夹内容
- 启动下载
现在，单独运行部分代码，它就完成了需要的操作。然而，当把所有这些放在一起时，它会在扫描子文件夹中的docx文件时死亡。
我的文件夹结构如下：
/样品/
- /IT/it1.docx
- /F&B/fb1.docx
- /FO/fo1.docx
- 示例1.docx
问题似乎发生在级别1文件夹的is_dir（$dir）部分。你知道是什么原因造成的吗？

我认为这是因为Scandir（）会产生类似的东西
`Array
(
...
[9] => .
[10] => ..`
在数组的末尾，当你检查这些是否是文件夹时，可能会发生错误并导致死亡。
