// Create a RecursiveIteratorIterator object to iterate over the directory
$iterator = new RecursiveIteratorIterator($directoryIterator, RecursiveIteratorIterator::SELF_FIRST);

// Loop through the iterator to search for specific files or directories
foreach ($iterator as $file) {
    if ($file->isDir()) {
        echo 'Directory: ' . $file->getPathname() . PHP_EOL;
    } else {
