What are best practices for handling empty directories when working with RecursiveIteratorIterator in PHP?

When using RecursiveIteratorIterator in PHP, empty directories may not be included in the iteration process by default. To handle this, you can set the RecursiveIteratorIterator flags to include empty directories by using the SELF_FIRST flag. This will ensure that even empty directories are included in the iteration. 

$directory = new RecursiveDirectoryIterator('/path/to/directory');
$iterator = new RecursiveIteratorIterator($directory, RecursiveIteratorIterator::SELF_FIRST);

foreach ($iterator as $file) {
    echo $file . PHP_EOL;
}
