推荐答案

PHP 5具有 RecursiveDirectoryIterator .

PHP 5 has the RecursiveDirectoryIterator.

该手册有一个基本示例:

The manual has a basic example:

<?php

$directory = '/system/infomation/';

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($directory));

while($it->valid()) {

    if (!$it->isDot()) {

        echo 'SubPathName: ' . $it->getSubPathName() . "\n";
        echo 'SubPath:     ' . $it->getSubPath() . "\n";
        echo 'Key:         ' . $it->key() . "\n\n";
    }

    $it->next();
}

?>

编辑-这是一个稍微高级的示例(仅略有增加)，它产生的输出类似于您想要的输出(即文件夹名和文件名).

Edit -- Here's a slightly more advanced example (only slightly) which produces output similar to what you want (i.e. folder names then files).

// Create recursive dir iterator which skips dot folders
$dir = new RecursiveDirectoryIterator('./system/information',
    FilesystemIterator::SKIP_DOTS);

// Flatten the recursive iterator, folders come before their files
$it  = new RecursiveIteratorIterator($dir,
    RecursiveIteratorIterator::SELF_FIRST);

// Maximum depth is 1 level deeper than the base folder
$it->setMaxDepth(1);

// Basic loop displaying different messages based on file or folder
foreach ($it as $fileinfo) {
    if ($fileinfo->isDir()) {
        printf("Folder - %s\n", $fileinfo->getFilename());
    } elseif ($fileinfo->isFile()) {
        printf("File From %s - %s\n", $it->getSubPath(), $fileinfo->getFilename());
    }
}
