Dirs and Files

[The Hobo]

I'm running this code:

if ($handle = opendir('/home/vbshelf/public_html')) {
    $d = 0; $f = 0;
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            if (is_dir($file)) {
                $dirs[$d] = $file;
                $d = $d + 1;
            } else {
                $files[$f] = $file;
                $f = $f + 1;
            }
        }
    }
    
    closedir($handle);
    sort($dirs);
    sort($files);
    for ($i = 0; $i < count($dirs); $i++) {
        echo "<b>" . $dirs[$i] . "</b><br>\n";
    }
    for ($i = 0; $i < count($files); $i++) {
        echo $files[$i] . "<br>\n";
    }
} 

This is the only thing I could come up with to sort the directories and files in alphabetical order. Is this the best way to do it, or is there an easier approach?
