Count number of sub-folders in folder

PHP Code

<?php
    echo '<ul class="DirView">';
    $path = "../Desktop/";
    $dir = new DirectoryIterator($path);
    foreach ($dir as $fileinfo) {
        if ($fileinfo->isDir() && !$fileinfo->isDot()) {
            echo '<li>'.$fileinfo->getFilename().'</li>';
        }
    }
    echo '</ul>';
?>

Problem

I wish to be able to count the number of folders in my chosen location to do more with this script performing a whilst loop for the amount of sub-folders there are.

count($dir) would be the easiest solution, but unfortunately it doesn't work here. (always 1)

So here is the solution with a counter variable:

<?php
    echo '<ul class="DirView">';
    $path = "..";
    $dir = new DirectoryIterator($path);
    $counter = 0;
    foreach ($dir as $fileinfo) {
        if ($fileinfo->isDir() && !$fileinfo->isDot()) {
            echo '<li>'.$fileinfo->getFilename().'</li>';
            $counter++;
            // do your while loop here
        }
    }
    echo '</ul>';
    echo "There are $counter files in this directory.";
?>
