How can PHP code be optimized for better performance when parsing folder structures?

When parsing folder structures in PHP, it is important to optimize the code for better performance by reducing unnecessary function calls and loops. One way to achieve this is by using the RecursiveDirectoryIterator and RecursiveIteratorIterator classes provided by PHP, which allow for efficient traversal of directory structures. 

// Optimize PHP code for parsing folder structures using RecursiveDirectoryIterator and RecursiveIteratorIterator

$directory = '/path/to/directory';

$iterator = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator($directory, RecursiveDirectoryIterator::SKIP_DOTS),
    RecursiveIteratorIterator::SELF_FIRST
);

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