Listing All the Folders Subfolders and Files in a Directory Using PHP

Listing all the folders subfolders and files in a directory using php

function listFolderFiles($dir){
    $ffs = scandir($dir);

    unset($ffs[array_search('.', $ffs, true)]);
    unset($ffs[array_search('..', $ffs, true)]);

    // prevent empty ordered elements
    if (count($ffs) < 1)
        return;

    echo '<ol>';
    foreach($ffs as $ff){
        echo '<li>'.$ff;
        if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);
        echo '</li>';
    }
    echo '</ol>';
}

listFolderFiles('Main Dir');

List all the files and folders in a Directory with PHP recursive function

Get all the files and folders in a directory, don't call function when you have . or ...

Your code :

<?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'));

Output (example) :

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)

How to list directories, sub-directories and all files in php

Use scandir to see all stuff in the directory and is_file to check if the item is file or next directory, if it is directory, repeat the same thing over and over.

So, this is completely new code.

function listIt($path) {
$items = scandir($path);

foreach($items as $item) {

    // Ignore the . and .. folders
    if($item != "." AND $item != "..") {
        if (is_file($path . $item)) {
            // this is the file
            echo "-> " . $item . "<br>";
        } else {
            // this is the directory

            // do the list it again!
            echo "---> " . $item;
            echo "<div style='padding-left: 10px'>";
            listIt($path . $item . "/");
            echo "</div>";
        }
    }
  }
}

echo "<div style='padding-left: 10px'>";
listIt("/");
echo "</div>";

You can see the live demo here in my webserver, btw, I will keep this link just for a second

When you see the "->" it's an file and "-->" is a directory

The pure code with no HTML:

function listIt($path) {
$items = scandir($path);

foreach($items as $item) {
    // Ignore the . and .. folders
    if($item != "." AND $item != "..") {
        if (is_file($path . $item)) {
            // this is the file
            // Code for file
        } else {
            // this is the directory
            // do the list it again!
            // Code for directory
            listIt($path . $item . "/");
        }
    }
  }
}

listIt("/");

the demo can take a while to load, it's a lot of items.

How to list all files in folders and sub-folders using scandir and display them as an option in select?

While the other answers are fine and correct, allow me to add my solution as well:

function dirToOptions($path = __DIR__, $level = 0) {
    $items = scandir($path);
    foreach($items as $item) {
        // ignore items strating with a dot (= hidden or nav)
        if (strpos($item, '.') === 0) {
            continue;
        }

        $fullPath = $path . DIRECTORY_SEPARATOR . $item;
        // add some whitespace to better mimic the file structure
        $item = str_repeat(' ', $level * 3) . $item;
        // file
        if (is_file($fullPath)) {
            echo "<option>$item</option>";
        }
        // dir
        else if (is_dir($fullPath)) {
            // immediatly close the optgroup to prevent (invalid) nested optgroups
            echo "<optgroup label='$item'></optgroup>";
            // recursive call to self to add the subitems
            dirToOptions($fullPath, $level + 1);
        }
    }

}

echo '<select>';
dirToOptions();
echo '</select>';

It uses a recursive call to fetch the subitems. Note that I added some whitespace before each item to better mimic the file structure. Also I closed the optgroup immediatly, to prevent ending up with nested optgroup elements, which is invalid HTML.

PHP Get all subdirectories of a given directory

Option 1:

You can use glob() with the GLOB_ONLYDIR option.

Option 2:

Another option is to use array_filter to filter the list of directories. However, note that the code below will skip valid directories with periods in their name like .config.

$dirs = array_filter(glob('*'), 'is_dir');
print_r($dirs);

PHP - reading folder, all subfolders, and files in subfolders

I think your issue comes from here :

while (false !== ($file = readdir($handle))) // it reads again the same directory as it did in the first while loop

Try to replace it with

if ($sub_handle = opendir($dir . $folder)) {
    while (false !== ($file = readdir($sub_handle))) {
        ...
    }
    closedir($sub_handle);
}

Also, in your case, I would use php glob() function

See a working example for your case :

$dir = './inspections/';
if ($handle = opendir($dir)) {
    $blacklist = array('.', '..', 'default', 'default.php', 'desc.txt');
    while (false !== ($folder = readdir($handle))) {
        if (!in_array($folder, $blacklist)) {
            foreach (glob($dir . $folder . "/*.png") as $filename) {
                echo "$filename was found !";
                echo "\r\n";
            }
        }
    }
    closedir($handle);
}

Output :

./inspections/location_4/img_1.png was found !
./inspections/location_4/img_2.png was found !
./inspections/location_4/img_3.png was found !
./inspections/location_4/img_4.png was found !
./inspections/location_4/img_5.png was found !
./inspections/location_4/img_6.png was found !
./inspections/location_3/img_1.png was found !
./inspections/location_3/img_2.png was found !
./inspections/location_3/img_3.png was found !
./inspections/location_3/img_4.png was found !
./inspections/location_3/img_5.png was found !
./inspections/location_3/img_6.png was found !
./inspections/location_2/img_1.png was found !
./inspections/location_2/img_2.png was found !
./inspections/location_2/img_3.png was found !
./inspections/location_2/img_4.png was found !
./inspections/location_2/img_5.png was found !
./inspections/location_2/img_6.png was found !
./inspections/location_1/img_1.png was found !
./inspections/location_1/img_2.png was found !
./inspections/location_1/img_3.png was found !
./inspections/location_1/img_4.png was found !
./inspections/location_1/img_5.png was found !
./inspections/location_1/img_6.png was found !

EDIT

To loop in the /inspections/location1/thumbs/ directories, this would work :

foreach (glob($dir . $folder . "/thumbs/*.png") as $filename) {
    echo "$filename was found !";
    echo "\r\n";
}

RE-EDIT

To glob multiple folders with the glob() function, your code should look like :

foreach (glob($dir.$folder."{/thumbs/*.png,/*.png}", GLOB_BRACE) as $filename) {
    echo "$filename was found !";
    echo "\r\n";
}

List subfolders with number of files PHP

Using PHP recursive function you can get simple array for folders.

PHP

<?php
    $array=array();
    function getCount($path){
        $count=0;
        global $array;
        //$count=count(glob($path."/*"));
        foreach(new DirectoryIterator($path) as $fileInfo){
            if($fileInfo->isDir()){
                if($fileInfo->isDot()) continue;
                if(array_key_exists($fileInfo->getFilename(),$array)){
                    $array[$fileInfo->getFilename()] = array(
                        'is_file_directory' => 'file',
                        'count' => getCount($fileInfo->getPathname())
                    );
                }
                else{
                    $array[$fileInfo->getFilename()] = array(
                        'is_file_directory' => 'directory',
                        'count' => getCount($fileInfo->getPathname())
                    );
                }
            }
            else{
                $array[$fileInfo->getFilename()] = array(
                    'is_file_directory' => 'file',
                    'count' => 0
                );
                $count++;
            }
        }
        return $count;
    }
?>

How to use : getCount('folder/inner_folder'); print_r($array);

Listing out files in PHP (ONLY the files) as links from all subdirectories of a directory

Try using glob():

<?php
    foreach(glob('path-to/UPLOAD_FOLDER/*') as $subDirectory) {         
        foreach(glob($subDirectory'./*') as $file) {

            // do what you want with file here... example:
            $file_list .= $file.'<br>';                             
        }                               
    }
    echo $file_list;
?>
