Question

1）以下是我的目录结构 -

array

2）我想要的是files and directories Array ( [files] => Array ( [0] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file1.php [1] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file2.php [2] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file3.php [3] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1/file4.php [4] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1/file5.php [5] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1/folder2/file6.php [6] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder3/file7.php [7] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder3/file8.php ) [directories] => Array ( [0] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1 [1] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1/folder2 [2] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder3 ) ) -

Array
(
[files] => Array
    (
        [0] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file1.php
        [1] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file2.php
        [2] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/file3.php
    )

[directories] => Array
    (
        [0] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder1
        [1] => /home/ubuntu/projects/xyz.com/code/ciapp/views/pages/folder3
    )
)

3）我得到的东西（只有1级） -

function get_files_directories($directory, $a = array())
{
    $dirs = scandir($directory, 1);
    $arr = $a;

    foreach($dirs as $dir)
    {
       if($dir != "." && $dir != '..')
       {
           $new_dir = $directory.'/'.$dir;
           if(is_dir($new_dir))
           {
               $arr['directories'][] = $new_dir;
               get_files_directories($new_dir, $arr);
           }
           else
           {
               $arr['files'][] = $new_dir;
           }
       }
    }

    return $arr;
}

$my_dir = "/home/ubuntu/projects/xyz.com/code/ciapp/views/pages";
$files_dirs = get_files_directories($my_dir);

echo '<pre>'; print_r($files_dirs);

4）我的功能 -

{{1}}

我在这里错过了什么？帮助将不胜感激。谢谢你：）

Answer 1

使用您的路径切换$path，这应该有效。 SPL包含递归目录遍历所需的所有类，不需要自己滚动。

<?php

$path   = '.';
$result = array('files' => array(), 'directories' => array());

$DirectoryIterator = new RecursiveDirectoryIterator($path);
$IteratorIterator  = new RecursiveIteratorIterator($DirectoryIterator, RecursiveIteratorIterator::SELF_FIRST);
foreach ($IteratorIterator as $file) {

    $path = $file->getRealPath();
    if ($file->isDir()) {
        $result['directories'][] = $path;
    } elseif ($file->isFile()) {
        $result['files'][] = $path;
    }

}

print_r($result);

有关详细信息，请参阅PHP文档：RecursiveDirectoryIterator，RecursiveIteratorIterator＆amp; SplFileInfo是很好的起点！

Answer 2

使用FilesystemIterator可能会更快一点：

function getDirectoryList($dir) {
    $dirList = $fileList = array();
    $iter = new FilesystemIterator($dir, FilesystemIterator::SKIP_DOTS);

    foreach($iter as $file) {
        if($file->isDir()) {
            $dirList[$file->getFilename()] = getDirectoryList($file->getPathname());
        } else {
            $fileList[$file->getFilename()] = $file->getFilename();
        }
    }
    uksort($dirList, "strnatcmp");
    natsort($fileList);
    return $dirList + $fileList;
}

此函数将为您提供一个与目录结构完全相同的多维数组，也可以更容易使用。

Answer 3

它是递归调用，您可以将返回值附加到数组或处理数组引用：

if(is_dir($new_dir))
{
    $arr['directories'][] = $new_dir;
    get_files_directories($new_dir, $arr); //assign or return
}

-

function get_files_directories($directory, &$arr)

Answer 4

您应该指定从重复调用返回的“arr”，或者您应该通过引用传入数组。（参见参考文献：http://php.net/manual/en/language.references.pass.php）

通过引用传递：get_files_directories（$ new_dir，＆amp; $ arr）;

PHP递归函数：获取目录及其子目录中的所有文件和目录
