我在如何做到这一点上有一个真正的脱节——部分原因是我没有使用文件系统的经验。我正在尝试创建一个脚本来导航文件夹下面的文件。该文件当前通过列出其所在目录的内容（又名“.”）来工作。我不知道如何让它列出下面文件夹的内容以及最好的方法。我的脚本需要如何修改才能达到这个目标？

// sets ordering variables
$a = $_GET['a'];

// are you allowed to delete?
if($_SESSION['delete'] == "ON") {
    $do_del = true;
    }
else {
    $do_del = false;
    }

// scandir to opendir coversion from stackoverflow.com/questions/6823489/
$files_dir = ".";
$dir_handle = opendir($files_dir);
while ($dir_temp = readdir($dir_handle)) {
    $arr_dir[] = $dir_temp;
    }
closedir($dir_handle);

使您的脚本成为接受路径的函数。

然后在 if(is_dir($file)) 内部的 while 语句中调用您的函数并将其传递给 $file。

例如，

function myFileSize($value) {...}
function myDate($value) {...}

function list_contents($path)
{
    $dir_name = $path;
    .
    .
    .
    $dir = opendir($path);
    .
    .
    .
    while ($file = readdir($dir)) {
        // do some stuff
        if (is_dir($file)) {
            list_contents($file);
        }
    }
}

根据您要执行的操作，您需要修改 list_contents() 函数的输出以使用递归。您可以使用数组生成一些树结构，然后稍后将树打印出来，例如：

// return an array representing tree structure
function list_contents($path, &$tree)
{
    // ...
    while ($file = readdir($dir)) {
        $tree[$path][] = $file;
        if (is_dir($file)) {
            list_contents($file, $tree[$path]);
        }
    }

    return $tree;
}

function print_tree($tree)
{
    // code to display array using tree structure
}

$path = '.';
$dir_name = $path;

$tree_array = array();
$tree = list_contents($path, $tree_array)

print_tree($tree);

或者您可以添加一个变量来计算方法中的级别数是

function list_contents($path, $level = 0)
{
    //...
    // indent output text by $level number of tabs
    while($file = readdir($dir) {
        if (is_dir($file)) {
            list_contents($file, $level++)
        }
    }
}

list_contents($path);

输出看起来像

> Root
    > Folder1 in root
    > Folder2 in root
        > Folder1 in Folder2
        > Folder2 in Folder2
    > Folder3 in root
        > Folder1 in Folder3
              > Folder1 in Folder1/Folder3
        > File1 in Folder1
    > File1 in root
    > File2 in root

作为建议，我会采用与获取文件信息或操作文件相关的任何函数并将它们放在自己的文件 file_functions.php 中，然后将其包含在脚本的顶部。
