PHP Get all subdirectories of a given directory

Question

How can I get all sub-directories of a given directory without files, .(current directory) or ..(parent directory) and then use each directory in a function?

Answer 1

You can use the glob() function to do this.

Here is some documentation on it: http://php.net/manual/en/function.glob.php

Answer 2

Find all PHP files recursively. The logic should be simple enough to tweak and it aims to be fast(er) by avoiding function calls.

function get_all_php_files($directory) {
    $directory_stack = array($directory);
    $ignored_filename = array(
        '.git' => true,
        '.svn' => true,
        '.hg' => true,
        'index.php' => true,
    );
    $file_list = array();
    while ($directory_stack) {
        $current_directory = array_shift($directory_stack);
        $files = scandir($current_directory);
        foreach ($files as $filename) {
            //  Skip all files/directories with:
            //      - A starting '.'
            //      - A starting '_'
            //      - Ignore 'index.php' files
            $pathname = $current_directory . DIRECTORY_SEPARATOR . $filename;
            if (isset($filename[0]) && (
                $filename[0] === '.' ||
                $filename[0] === '_' ||
                isset($ignored_filename[$filename])
            )) 
            {
                continue;
            }
            else if (is_dir($pathname) === TRUE) {
                $directory_stack[] = $pathname;
            } else if (pathinfo($pathname, PATHINFO_EXTENSION) === 'php') {
                $file_list[] = $pathname;
            }
        }
    }
    return $file_list;
}

Answer 3

Almost the same as in your previous question:

$iterator = new RecursiveIteratorIterator(
                new RecursiveDirectoryIterator($yourStartingPath), 
            RecursiveIteratorIterator::SELF_FIRST);

foreach($iterator as $file) {
    if($file->isDir()) {
        echo strtoupper($file->getRealpath()), PHP_EOL;
    }
}

Replace strtoupper with your desired function.

Answer 4

You can try this function (PHP 7 required)

function getDirectories(string $path) : array
{
    $directories = [];
    $items = scandir($path);
    foreach ($items as $item) {
        if($item == '..' || $item == '.')
            continue;
        if(is_dir($path.'/'.$item))
            $directories[] = $item;
    }
    return $directories;
}

Answer 5

The Spl DirectoryIterator class provides a simple interface for viewing the contents of filesystem directories.

$dir = new DirectoryIterator($path);
foreach ($dir as $fileinfo) {
    if ($fileinfo->isDir() && !$fileinfo->isDot()) {
        echo $fileinfo->getFilename().'<br>';
    }
}

Answer 6

In Array:

function expandDirectoriesMatrix($base_dir, $level = 0) {
    $directories = array();
    foreach(scandir($base_dir) as $file) {
        if($file == '.' || $file == '..') continue;
        $dir = $base_dir.DIRECTORY_SEPARATOR.$file;
        if(is_dir($dir)) {
            $directories[]= array(
                    'level' => $level
                    'name' => $file,
                    'path' => $dir,
                    'children' => expandDirectoriesMatrix($dir, $level +1)
            );
        }
    }
    return $directories;
}

//access:

$dir = '/var/www/';
$directories = expandDirectoriesMatrix($dir);

echo $directories[0]['level']                // 0
echo $directories[0]['name']                 // pathA
echo $directories[0]['path']                 // /var/www/pathA
echo $directories[0]['children'][0]['name']  // subPathA1
echo $directories[0]['children'][0]['level'] // 1
echo $directories[0]['children'][1]['name']  // subPathA2
echo $directories[0]['children'][1]['level'] // 1

Example to show all:

function showDirectories($list, $parent = array())
{
    foreach ($list as $directory){
        $parent_name = count($parent) ? " parent: ({$parent['name']}" : '';
        $prefix = str_repeat('-', $directory['level']);
        echo "$prefix {$directory['name']} $parent_name <br/>";  // <-----------
        if(count($directory['children'])){
            // list the children directories
            showDirectories($directory['children'], $directory);
        }
    }
}

showDirectories($directories);

// pathA
// - subPathA1 (parent: pathA)
// -- subsubPathA11 (parent: subPathA1)
// - subPathA2 
// pathB
// pathC
