Search and list specific directories only?

Question

I want to search and list specific folders only and no matter how deep these folders are kept.

For instance, below is how I structure them,

local/
     app/
        master/
             models/
             views/
        slaves/
             models/
             views/
     scr/
     models/
     index.php

And I just want to list the folder of models into an array,

local/app/master/models/
local/app/slaves/models/
local/models/

My working code,

$directories = array();

$results = array_diff( scandir("local"), array(".", "..") );

foreach ($results as $result)
{
    if (is_dir("local/".$result)) {

        $directories[] = $result;
    }
}

var_dump($directories);

result,

array
  0 => string 'app' (length=3)
  1 => string 'models' (length=6)
  2 => string 'src' (length=3)

Any ideas?

// Create an object that allows us to iterate directories recursively
// Stolen from here: 
// http://www.php.net/manual/en/class.recursivedirectoryiterator.php#102587
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir),
                                          RecursiveIteratorIterator::CHILD_FIRST);

// This will hold the result
$result = array();

// Loop the directory contents
foreach ($iterator as $path) {

  // If object is a directory and matches the search term ('models')...
  if ($path->isDir() && $path->getBasename() === 'models') {

    // Add it to the result array
    $result[] = (string) $path;

  }

}

print_r($result);
