使用PHP递归函数列出目录中的所有文件和文件夹

Question

我试图浏览目录中的所有文件，如果有目录，请浏览所有文件，依此类推，直到没有更多目录要去。每个处理过的项目都将添加到下面函数的结果数组中。虽然我不知道我能做什么/我做错了什么但它不能正常工作，但是当处理下面这段代码时，浏览器运行速度非常慢，感谢任何帮助！谢谢！

代码：

    function getDirContents($dir){
        $results = array();
        $files = scandir($dir);

            foreach($files as $key => $value){
                if(!is_dir($dir. DIRECTORY_SEPARATOR .$value)){
                    $results[] = $value;
                } else if(is_dir($dir. DIRECTORY_SEPARATOR .$value)) {
                    $results[] = $value;
                    getDirContents($dir. DIRECTORY_SEPARATOR .$value);
                }
            }
    }

    print_r(getDirContents('/xampp/htdocs/WORK'));

Answer 1

获取目录中的所有文件和文件夹，在.或..时不要调用函数。

您的代码：

<?php
function getDirContents($dir, &$results = array()){
    $files = scandir($dir);

    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            $results[] = $path;
        } else if($value != "." && $value != "..") {
            getDirContents($path, $results);
            $results[] = $path;
        }
    }

    return $results;
}

var_dump(getDirContents('/xampp/htdocs/WORK'));

输出（示例）：

array (size=12)
  0 => string '/xampp/htdocs/WORK/iframe.html' (length=30)
  1 => string '/xampp/htdocs/WORK/index.html' (length=29)
  2 => string '/xampp/htdocs/WORK/js' (length=21)
  3 => string '/xampp/htdocs/WORK/js/btwn.js' (length=29)
  4 => string '/xampp/htdocs/WORK/js/qunit' (length=27)
  5 => string '/xampp/htdocs/WORK/js/qunit/qunit.css' (length=37)
  6 => string '/xampp/htdocs/WORK/js/qunit/qunit.js' (length=36)
  7 => string '/xampp/htdocs/WORK/js/unit-test.js' (length=34)
  8 => string '/xampp/htdocs/WORK/xxxxx.js' (length=30)
  9 => string '/xampp/htdocs/WORK/plane.png' (length=28)
  10 => string '/xampp/htdocs/WORK/qunit.html' (length=29)
  11 => string '/xampp/htdocs/WORK/styles.less' (length=30)

Answer 2

$rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('path/to/folder'));

$files = array(); 

foreach ($rii as $file) {

    if ($file->isDir()){ 
        continue;
    }

    $files[] = $file->getPathname(); 

}



var_dump($files);

这将为您带来所有带路径的文件。

Answer 3

它的缩短版本：

function getDirContents($path) {
    $rii = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));

    $files = array(); 
    foreach ($rii as $file)
        if (!$file->isDir())
            $files[] = $file->getPathname();

    return $files;
}

var_dump(getDirContents($path));

Answer 4

获取所有文件带过滤器 （第二个参数）和目录中的文件夹，当您有.或{时，请不要调用函数{1}}。

您的代码：

..

输出（示例）：

<?php
function getDirContents($dir, $filter = '', &$results = array()) {
    $files = scandir($dir);

    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value); 

        if(!is_dir($path)) {
            if(empty($filter) || preg_match($filter, $path)) $results[] = $path;
        } elseif($value != "." && $value != "..") {
            getDirContents($path, $filter, $results);
        }
    }

    return $results;
} 

// Simple Call: List all files
var_dump(getDirContents('/xampp/htdocs/WORK'));

// Regex Call: List php files only
var_dump(getDirContents('/xampp/htdocs/WORK', '/\.php$/'));

Answer 5

我的建议没有丑陋＆＃34; foreach＆＃34;控制结构是

array_keys($allFiles);

您可能只想提取文件路径，您可以通过以下方式执行此操作：

import Data.Int (Int32)
import Data.Bits ((.|.),(.&.),unsafeShiftL)
import Data.Word (Word32)
import Data.Binary
import qualified Data.ByteString as BS
import qualified Data.ByteString.Unsafe as BSU

int32_24be :: BS.ByteString -> Int32
int32_24be = \s ->
  let x =   unsafeShiftL (fromIntegral (BSU.unsafeIndex s 0)) 16
        .|. unsafeShiftL (fromIntegral (BSU.unsafeIndex s 1))  8
        .|.               fromIntegral (BSU.unsafeIndex s 2)
        :: Int32
      y = fromIntegral x :: Word32
  in fromIntegral (if x .&. 0x00800000 > 0 then y .|. 0xFF000000 else y .&. 0x00FFFFFF)

getFloat :: BS.ByteString -> Float
getFloat = (/ 2^^23) . fromIntegral . int32_24be

仍然有4行代码，但比使用循环或其他东西更直接。

Answer 6

这是Hors回答的修改版本，对我的情况稍微好一点，因为它删除了传递的基本目录，并且有一个递归开关，可以设置为false，这也很方便。另外为了使输出更具可读性，我将文件和子目录文件分开，因此首先添加文件然后添加子目录文件（参见结果我的意思。）

我尝试了一些其他的方法和建议，这就是我最终的结果。我有另一个非常相似的工作方法，但似乎失败的地方有一个没有文件的子目录，但该子目录有一个带有文件的子目录，它没有扫描子目录中的文件 - 所以某些答案可能需要针对该案例进行测试。）...无论如何我认为我也会在这里发布我的版本以防万一有人在寻找......

function get_filelist_as_array($dir, $recursive = true, $basedir = '', $include_dirs = false) {
    if ($dir == '') {return array();} else {$results = array(); $subresults = array();}
    if (!is_dir($dir)) {$dir = dirname($dir);} // so a files path can be sent
    if ($basedir == '') {$basedir = realpath($dir).DIRECTORY_SEPARATOR;}

    $files = scandir($dir);
    foreach ($files as $key => $value){
        if ( ($value != '.') && ($value != '..') ) {
            $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
            if (is_dir($path)) {
                // optionally include directories in file list
                if ($include_dirs) {$subresults[] = str_replace($basedir, '', $path);}
                // optionally get file list for all subdirectories
                if ($recursive) {
                    $subdirresults = get_filelist_as_array($path, $recursive, $basedir, $include_dirs);
                    $results = array_merge($results, $subdirresults);
                }
            } else {
                // strip basedir and add to subarray to separate file list
                $subresults[] = str_replace($basedir, '', $path);
            }
        }
    }
    // merge the subarray to give the list of files then subdirectory files
    if (count($subresults) > 0) {$results = array_merge($subresults, $results);}
    return $results;
}

我想有一件事要小心，不要在调用它时将$ basedir值传递给此函数...大多数只是传递$ dir（或者传递文件路径现在也可以）并且可选$ recursive as false如果需要的话。结果：

[0] => demo-image.png
[1] => filelist.php
[2] => tile.png
[3] => 2015\header.png
[4] => 2015\08\background.jpg

享受！好的，回到程序我实际上正在使用它...

UPDATE 添加了额外的参数，用于在文件列表中包含目录（记住需要传递其他参数才能使用它。）例如。

$results = get_filelist_as_array($dir, true, '', true);

Answer 7

这个解决方案为我完成了这项工作。 RecursiveIteratorIterator以递归方式列出所有目录和文件但未排序。该程序过滤列表并对其进行排序。

我确信有一种方法可以写得更短;随时改进它。 它只是一个代码片段。你可能想把它拉到你的目的。

<?php

$path = '/pth/to/your/directories/and/files';
// an unsorted array of dirs & files
$files_dirs = iterator_to_array( new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path),RecursiveIteratorIterator::SELF_FIRST) );

echo '<html><body><pre>';
// create a new associative multi-dimensional array with dirs as keys and their files
$dirs_files = array();
foreach($files_dirs as $dir){
 if(is_dir($dir) AND preg_match('/\/\.$/',$dir)){
  $d = preg_replace('/\/\.$/','',$dir);
  $dirs_files[$d] = array();
  foreach($files_dirs as $file){
   if(is_file($file) AND $d == dirname($file)){
    $f = basename($file);
    $dirs_files[$d][] = $f;
   }
  }
 }
}
//print_r($dirs_files);

// sort dirs
ksort($dirs_files);

foreach($dirs_files as $dir => $files){
 $c = substr_count($dir,'/');
 echo  str_pad(' ',$c,' ', STR_PAD_LEFT)."$dir\n";
 // sort files
 asort($files);
 foreach($files as $file){
  echo str_pad(' ',$c,' ', STR_PAD_LEFT)."|_$file\n";
 }
}
echo '</pre></body></html>';

?>

Answer 8

这将打印给定目录中所有文件的完整路径，您也可以将其他回调函数传递给recursiveDir。

function printFunc($path){
    echo $path."<br>";
}

function recursiveDir($path, $fileFunc, $dirFunc){
    $openDir = opendir($path);
    while (($file = readdir($openDir)) !== false) {
        $fullFilePath = realpath("$path/$file");
        if ($file[0] != ".") {
            if (is_file($fullFilePath)){
                if (is_callable($fileFunc)){
                    $fileFunc($fullFilePath);
                }
            } else {
                if (is_callable($dirFunc)){
                    $dirFunc($fullFilePath);
                }
                recursiveDir($fullFilePath, $fileFunc, $dirFunc);
            }
        }
    }
}

recursiveDir($dirToScan, 'printFunc', 'printFunc');

以下是我提出的内容，而且代码行数不多

function show_files($start) {
    $contents = scandir($start);
    array_splice($contents, 0,2);
    echo "<ul>";
    foreach ( $contents as $item ) {
        if ( is_dir("$start/$item") && (substr($item, 0,1) != '.') ) {
            echo "<li>$item</li>";
            show_files("$start/$item");
        } else {
            echo "<li>$item</li>";
        }
    }
    echo "</ul>";
}

show_files('./');

输出类似

的内容

..idea
.add.php
.add_task.php
.helpers
 .countries.php
.mysqli_connect.php
.sort.php
.test.js
.test.php
.view_tasks.php

**点是无序列表的点。

希望这有帮助。

Answer 11

如果您使用 Laravel，您可以使用 getAllFiles 门面上的 Storage 方法递归获取所有文件，如此处的文档所示：https://laravel.com/docs/8.x/filesystem#get-all-files-within-a-directory。

use Illuminate\Support\Facades\Storage;

class TestClass {

    public function test() {
        // Gets all the files in the 'storage/app' directory.
        $files = Storage::getAllFiles(storage_path('app'))
    }

}

@ A-312的解决方案可能会导致内存问题，因为如果/xampp/htdocs/WORK包含许多文件和文件夹，它可能会创建一个巨大的数组。

如果您有PHP 7，则可以使用Generators并按以下方式优化PHP的内存：

function getDirContents($dir) {
    $files = scandir($dir);
    foreach($files as $key => $value){

        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            yield $path;

        } else if($value != "." && $value != "..") {
           yield from getDirContents($path);
           yield $path;
        }
    }
}

foreach(getDirContents('/xampp/htdocs/WORK') as $value) {
    echo $value."\n";
}

yield from

Answer 14

如果您希望以数组形式获取目录内容，而忽略隐藏的文件和目录，则可能会有所帮助。

function dir_tree($dir_path)
{
    $rdi = new \RecursiveDirectoryIterator($dir_path);

    $rii = new \RecursiveIteratorIterator($rdi);

    $tree = [];

    foreach ($rii as $splFileInfo) {
        $file_name = $splFileInfo->getFilename();

        // Skip hidden files and directories.
        if ($file_name[0] === '.') {
            continue;
        }

        $path = $splFileInfo->isDir() ? array($file_name => array()) : array($file_name);

        for ($depth = $rii->getDepth() - 1; $depth >= 0; $depth--) {
            $path = array($rii->getSubIterator($depth)->current()->getFilename() => $path);
        }

        $tree = array_merge_recursive($tree, $path);
    }

    return $tree;
}

结果将是类似的

dir_tree(__DIR__.'/public');

[
    'css' => [
        'style.css',
        'style.min.css',
    ],
    'js' => [
        'style.css',
        'style.min.css',
    ],
    'favicon.ico',
]

Answer 16

谁首先需要列出文件而不是文件夹（字母更早）。

可以使用以下功能。 这不是自调用功能。这样您将拥有目录列表，目录视图，文件 列表和文件夹列表也作为单独的数组。

我为此花了两天时间，也不希望有人也会为此浪费时间，希望对某人有所帮助。

function dirlist($dir){
    if(!file_exists($dir)){ return $dir.' does not exists'; }
    $list = array('path' => $dir, 'dirview' => array(), 'dirlist' => array(), 'files' => array(), 'folders' => array());

    $dirs = array($dir);
    while(null !== ($dir = array_pop($dirs))){
        if($dh = opendir($dir)){
            while(false !== ($file = readdir($dh))){
                if($file == '.' || $file == '..') continue;
                $path = $dir.DIRECTORY_SEPARATOR.$file;
                $list['dirlist_natural'][] = $path;
                if(is_dir($path)){
                    $list['dirview'][$dir]['folders'][] = $path;
                    // Bos klasorler while icerisine tekrar girmeyecektir. Klasorun oldugundan emin olalım.
                    if(!isset($list['dirview'][$path])){ $list['dirview'][$path] = array(); }
                    $dirs[] = $path;
                    //if($path == 'D:\Xampp\htdocs\exclusiveyachtcharter.localhost\wp-content\upgrade'){ press($path); press($list['dirview']); die; }
                }
                else{
                    $list['dirview'][$dir]['files'][] = $path;
                }
            }
            closedir($dh);
        }
    }

    // if(!empty($dirlist['dirlist_natural']))  sort($dirlist['dirlist_natural'], SORT_LOCALE_STRING); // delete safe ama gerek kalmadı.

    if(!empty($list['dirview'])) ksort($list['dirview']);

    // Dosyaları dogru sıralama yaptırıyoruz. Deniz P. - info[at]netinial.com

            $list['files'] = array_merge($list['files'], $file['files']);
            $list['dirlist'] = array_merge($list['dirlist'], $file['files']);
        }
        // Add empty folders to the list
        if(is_dir($path) && array_search($path, $list['dirlist']) === false){
            $list['dirlist'][] = $path;
        }
        if(isset($file['folders'])){
            $list['folders'] = array_merge($list['folders'], $file['folders']);
        }
    }

    //press(array_diff($list['dirlist_natural'], $list['dirlist'])); press($list['dirview']); die;

    return $list;
}

将输出类似这样的内容。

我通过一次检查迭代改进了Hors Sujet的优秀代码，以避免在结果数组中包含文件夹：

function getDirContents($dir, &$results = array()){

    $files = scandir($dir);

    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(is_dir($path) == false) {
            $results[] = $path;
        }
        else if($value != "." && $value != "..") {
            getDirContents($path, $results);
            if(is_dir($path) == false) {
                $results[] = $path;
            }   
        }
    }
    return $results;

}

这里有我的例子

列出使用PHP递归函数读取的目录csv（文件）中的所有文件和文件夹

<?php

/** List all the files and folders in a Directory csv(file) read with PHP recursive function */
function getDirContents($dir, &$results = array()){
    $files = scandir($dir);

    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            $results[] = $path;
        } else if($value != "." && $value != "..") {
            getDirContents($path, $results);
            //$results[] = $path;
        }
    }

    return $results;
}





$files = getDirContents('/xampp/htdocs/medifree/lab');//here folder name where your folders and it's csvfile;


foreach($files as $file){
$csv_file =$file;
$foldername =  explode(DIRECTORY_SEPARATOR,$file);
//using this get your folder name (explode your path);
print_r($foldername);

if (($handle = fopen($csv_file, "r")) !== FALSE) {

fgetcsv($handle); 
while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
$num = count($data);
for ($c=0; $c < $num; $c++) {
$col[$c] = $data[$c];
}
}
fclose($handle);
}

}

?>

这是我的：

function recScan( $mainDir, $allData = array() ) 
{ 
// hide files 
$hidefiles = array( 
".", 
"..", 
".htaccess", 
".htpasswd", 
"index.php", 
"php.ini", 
"error_log" ) ; 

//start reading directory 
$dirContent = scandir( $mainDir ) ; 

foreach ( $dirContent as $key => $content ) 
{ 
$path = $mainDir . '/' . $content ; 

// if is readable / file 
if ( ! in_array( $content, $hidefiles ) ) 
{ 
if ( is_file( $path ) && is_readable( $path ) ) 
{ 
$allData[] = $path ; 
} 

// if is readable / directory 
// Beware ! recursive scan eats ressources ! 
else 
if ( is_dir( $path ) && is_readable( $path ) ) 
{ 
/*recursive*/ 
$allData = recScan( $path, $allData ) ; 
} 
} 
} 

return $allData ; 
}
