如何在 PHP 中显示 dir 中的文件夹和子文件夹

发布于 2024-10-02 18:07:57 字数 1007 浏览 0 评论 0原文

我正在尝试获取包含文件夹和子文件夹的列表，我有以下内容，可以让我获取文件夹和子文件夹，但我需要像下面的示例一样对它进行排序，我一直在尝试，但我不知道如何获取大约。

Root/
Root/Images
Root/Images/UserImages

Root/Text/
Root/Text/User1/
Root/Text/User1/Folder2

但目前它的显示如下

Root/css/
tree/css/
js/
images/

PHP 代码：

    function ListFolder($path)
{

    $dir_handle = @opendir($path) or die("Unable to open $path");

    //Leave only the lastest folder name
    $dirname = end(explode("/", $path));

    //display the target folder.
    echo ("$dirname/");
    while (false !== ($file = readdir($dir_handle)))
    {
        if($file!="." && $file!="..")
        {
            if (is_dir($path."/".$file))
            {
                //Display a list of sub folders.
                ListFolder($path."/".$file);
                echo "<br>";
            }
        }
    }


    //closing the directory
    closedir($dir_handle);
}

    ListFolder("../");

谢谢

将目录名称收集到数组中，而不是直接回显它们。对数组使用 sort 并使用 foreach 循环来打印列表。

因此，您可以使用 $dirnames[] = $dirname; 而不是 echo ("$dirname/"); （使 $dirnames 全局化并在第一次调用之前初始化它） “列表文件夹”）。然后，在递归运行“ListFolder”之后，您将执行 sort($dirnames);，然后执行类似以下的输出：

foreach ($dirnames as $dirname)
{
  echo $dirname . '<br />';
}

Collect the directory names in an array instead of echoing them directly. Use sort on the array and a foreach-loop to print the list.

So instead of echo ("$dirname/"); you would use $dirnames[] = $dirname; (make $dirnames global and initialize it before your first call of "ListFolder"). Then after the recursive run of "ListFolder", you'd execute sort($dirnames); and then something like this for the output:

foreach ($dirnames as $dirname)
{
  echo $dirname . '<br />';
}

您可以使用 DirectoryIterator 或更好的 RecursiveDirectoryIterator 来实现您想要的php SPL.php

这是一个关于如何使用它的简单示例：

    $dir = '/path/to/directory';
    $result = array();

    if (is_dir($dir)) {
            $iterator = new RecursiveDirectoryIterator($dir);
            foreach (new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file) {                    
                if (!$file->isFile()) {
                    $result[] = 'path: ' . $file->getPath(). ',  filename: ' . $file->getFilename();
                }
            }

    }

这应该可以解决问题。祝你好运 ;）

you can achive what you want with the DirectoryIterator or better the RecursiveDirectoryIterator from the php SPL.

here is a quick example on how to use this:

    $dir = '/path/to/directory';
    $result = array();

    if (is_dir($dir)) {
            $iterator = new RecursiveDirectoryIterator($dir);
            foreach (new RecursiveIteratorIterator($iterator, RecursiveIteratorIterator::CHILD_FIRST) as $file) {                    
                if (!$file->isFile()) {
                    $result[] = 'path: ' . $file->getPath(). ',  filename: ' . $file->getFilename();
                }
            }

    }

This should do the trick. Good luck ;)

使用此代码，您将获得包含子目录的列表（但设置您的文件夹名称）

<?php
$path = realpath('yourfolder/examplefolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
        echo "$filename\n";
}
?>

with this code, you will get lists with subdirectories (but set your foldername)

<?php
$path = realpath('yourfolder/examplefolder');
foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path)) as $filename)
{
        echo "$filename\n";
}
?>
