How can the use of iterators in the SPL be beneficial when recursively reading directories in PHP?

When recursively reading directories in PHP, using iterators in the SPL (Standard PHP Library) can be beneficial as they provide a more efficient and convenient way to iterate over directory contents. By using iterators such as RecursiveDirectoryIterator and RecursiveIteratorIterator, you can easily traverse through directories and subdirectories without the need for complex recursive functions. This approach can simplify your code and improve performance when working with directory structures in PHP. 

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

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