How can the use of RecursiveDirectoryIterator in PHP improve the process of listing directories and subdirectories?

When listing directories and subdirectories in PHP, using RecursiveDirectoryIterator can simplify the process by allowing you to iterate through directories and subdirectories recursively without the need for complex nested loops or recursive functions. This can make the code more concise, easier to read, and less error-prone. 

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

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