PhP List Directories and SubDirectories - Assign Variable to each

Question

Good evening all,

I'm really struggling to find a way to list the directories of a given folder and also the subdirectories without adding in the files, as well as assigning them to a variable.

I've tried using getcwd, global, GLOB_ONLYDIR scandir, but can't get it to work out.

Is there anyway to assign each folder only to a variable?

$currentFolder2 =  getcwd();

foreach (glob($currentFolder2 . '/*' , GLOB_ONLYDIR) as $dir) {
    $files = glob($dir . '/*');
    echo '<pre>'; print_r($files);
    $link[0] = $files;
    foreach (glob($files . '/*' , GLOB_ONLYDIR) as $dir) {
        $subfiles = glob($dir . '/*');
        echo '<pre>'; print_r($subfiles);
        $sublink[0] = $files;
    }
}

What I need to produce is folder links:

-Link to Folder1
  -Link to Folder1-SubFolder1
  -Link to Folder1-SubFolder2
-Link to Folder2
  -Link to Folder2-SubFolder1
  -Link to Folder2-SubFolder2
-Link to Folder2
  -Link to Folder2-SubFolder1
  -Link to Folder2-SubFolder2

It's not laying out the way I planned and it's also returning html pages for some reason.

Have I over complicated the way I am going about it or have I gone completely the wrong way.

Thanks in advance

The logic:

1. Scan all files and folders with scandir() that gives you an array of everything
2. Check each object if it is directory with is_dir() function an if so, process it
3. Scan current directory for step 1 and 2 that will proccess sub directories

You need 2 scandir(): one for root and one for each parent folder

Sample code:

$content = ''; //For collecting future <li>'s
$folders = array_diff(scandir(ROOT_PATH, 1), array('.', '..', '.ftpquota', '.htaccess', 'index.html', 'index.php', 'error_log'));
if ($folders) {
    foreach ($folders as $folder) {
        if (is_dir(PATH_TO_$folder)) {
            $content .= '<li class="parent">'.$folder.'</li>'; //Add to any html you like
            
            //Now, scan this folder for subfolders:
            $subfolders = array_diff(scandir(ROOT_PATH.'/'.$folder, 1), array('.', '..', '.ftpquota', '.htaccess', 'index.html', 'index.php', 'error_log'));
            if ($subfolders) {
                foreach ($subfolders as $subfolder) {
                    if (is_dir(PATH_TO_$subfolder)) {
                        $content .= '<li class="child">'.$subfolder.'</li>'; //Add to any html you like
                    }
                }
            }
        }
    }
}
