How can the code snippet be optimized to improve the sorting functionality for the array of file names?

The issue with the current code snippet is that it is using a basic sorting function that may not handle file names correctly, especially if they contain numbers or special characters. To improve the sorting functionality for the array of file names, we can use the `natsort()` function in PHP, which sorts the file names in a more natural order. This will ensure that the file names are sorted as expected, taking into account numbers and special characters. 

$files = scandir('/path/to/directory');
unset($files[0], $files[1]); // remove . and ..
natsort($files);

foreach ($files as $file) {
    echo $file . "\n";
}
