使用 RecursiveDirectoryIterator 将目录和文件列出到数组中？

发布于 2024-09-15 09:59:30 字数 841 浏览 2 评论 0原文

我有一个具有以下结构的目录：

main/
- |- 图片/
  - |-- file1.jpg
  - |-- file2.jpg
  - |-- file3.jpg
- |- 文档/
  - |-- 私有/
    - |--- blahblahblah.docx
  - |-- 测试.doc
  - |-- 测试.xls
  - |-- 测试.txt

我可以创建一个函数来完成工作，但 RecursiveDirectoryIterator 类速度更快，内存使用量更少时间。如何使用 RecursiveDirectoryIterator 将这些目录列出到数组中，如下所示：

 array(  
    "main/" => array(  
        "images/" => array(  
            "file1.jpg",   
            "file2.jpg",   
            "file3.jpg"  
        ),   
        "documents/" => array(  
            "private/" => array(  
                "blahblahblah.docx"  
            ),  
            "test.doc",   
            "test.xls",   
            "test.txt"  
        )  
    )  
)

I'm having a directory with this structure :

main/
- |- images/
  - |-- file1.jpg
  - |-- file2.jpg
  - |-- file3.jpg
- |- documents/
  - |-- private/
    - |--- blahblahblah.docx
  - |-- test.doc
  - |-- test.xls
  - |-- test.txt

I can create a function to complete the work but the RecursiveDirectoryIterator class is much faster and less memory usage this time. How can I use RecursiveDirectoryIterator to list these directory into an array like this :

 array(  
    "main/" => array(  
        "images/" => array(  
            "file1.jpg",   
            "file2.jpg",   
            "file3.jpg"  
        ),   
        "documents/" => array(  
            "private/" => array(  
                "blahblahblah.docx"  
            ),  
            "test.doc",   
            "test.xls",   
            "test.txt"  
        )  
    )  
)

好吧，要递归地迭代 RecursiveIterator，您需要一个 RecursiveIteratorIterator （我知道这看起来多余，但事实并非如此）...

但是，对于您的特定情况（您希望生成一个结构而不是仅仅访问所有节点）），我认为常规递归会更适合...

function DirectoryIteratorToArray(DirectoryIterator $it) {
    $result = array();
    foreach ($it as $key => $child) {
        if ($child->isDot()) {
            continue;
        }
        $name = $child->getBasename();
        if ($child->isDir()) {
            $subit = new DirectoryIterator($child->getPathname());
            $result[$name] = DirectoryIteratorToArray($subit);
        } else {
            $result[] = $name;
        }
    }
    return $result;
}

编辑它以与非递归迭代器一起使用...

Well, to recursively iterate over the RecursiveIterator, you need a RecursiveIteratorIterator (I know it seems redundant, but it's not)...

However, for your particular case (Where you're looking to generate a structure rather than just visit all of the nodes), I think regular recursion would be better suited...

function DirectoryIteratorToArray(DirectoryIterator $it) {
    $result = array();
    foreach ($it as $key => $child) {
        if ($child->isDot()) {
            continue;
        }
        $name = $child->getBasename();
        if ($child->isDir()) {
            $subit = new DirectoryIterator($child->getPathname());
            $result[$name] = DirectoryIteratorToArray($subit);
        } else {
            $result[] = $name;
        }
    }
    return $result;
}

Edit it to work with non-recursive-iterators...
