How can PHP scripts be optimized to handle file/folder sorting efficiently and accurately on a website?

When sorting files and folders on a website using PHP, it is important to use efficient sorting algorithms to ensure quick and accurate results. One way to optimize this process is to use the built-in PHP function `scandir()` to read the contents of a directory and then sort the results using `usort()` with a custom comparison function. 

// Function to sort files and folders by name
function sortFiles($a, $b) {
    return strcmp(strtolower($a), strtolower($b));
}

// Get the list of files and folders in a directory
$dir = 'path/to/directory';
$files = scandir($dir);

// Remove . and .. from the list
$files = array_diff($files, array('.', '..'));

// Sort the files and folders
usort($files, 'sortFiles');

// Output the sorted list
foreach($files as $file) {
    echo $file . "<br>";
}
