Get subdirectories with Symfony 2 Finder component

Question

I am using the SF2 Finder Component to access a directory and grab the subdirectories inside it.

This is my code:

$finder = new Finder();
$dirs = $finder->directories()->in($this->getParameter('crmpicco.image_upload_path'));

The image_upload_path contains 3 directories: /small, /medium and /large

When I dump out the dirs attribute of what Finder returns I get:

  -dirs: array:1 [▼
    0 => "/var/www/crmpicco/20150805093500/app/files/import_images"
  ]

How can I modify this call to access /small, /medium and /large ?

dirs is a private property, how are you accessing it? Can you please post the code that dump the results? — A.L

I suggested to use a wildcard but after some tests, it seems that the result is the same with or without a wildcard.

With getIterator() I was able to lists all the children of a directory. On my filesystem there is a /var/www/ containing a html directory.

$finder = new \Symfony\Component\Finder\Finder();
$dirs = $finder->directories()->in('/var/www')->depth('< 1');
foreach($dirs->getIterator() as $iterator) {
    print_r($iterator);
}

This code return this:

Symfony\Component\Finder\SplFileInfo Object
(
    [relativePath:Symfony\Component\Finder\SplFileInfo:private] => 
    [relativePathname:Symfony\Component\Finder\SplFileInfo:private] => html
    [pathName:SplFileInfo:private] => /var/www/html
    [fileName:SplFileInfo:private] => html
)

So I think the problem is due to the fact that you use a private property of Finder instead of calling getIterator():
