List as array and modify the output

[Peuplarchie]

Good day to you all,
here I have a recursive directory lister that puts everything into an array.

Here is the code:

<?
function getDirectory($path = '.', $ignore = '') {
    $dirTree = array ();
    $dirTreeTemp = array ();
    $ignore[] = '.';
    $ignore[] = '..';

$dh = @opendir($path);

while (false !== ($file = readdir($dh))) {

    if (!in_array($file, $ignore)) {
        if (!is_dir("$path/$file")) {

            $dirTree["$path"][] = $file;

        } else {

            $dirTreeTemp = getDirectory("$path/$file", $ignore);
            if (is_array($dirTreeTemp))$dirTree = array_merge($dirTree, $dirTreeTemp);
        }
    }
}
closedir($dh);

return $dirTree;
}

$ignore = array('.htaccess', 'error_log', 'cgi-bin', 'php.ini', '.ftpquota');

$dirTree = getDirectory('Photos', $ignore);
?>
<pre>
    <?
    print_r($dirTree);
    ?>
</pre>

My question is how can I keep the same array and without looping again through the directories again list only the folder ?

If i can, how can I also list a text only the folder that does have folder in them and as a link the one that as files.

So when a link is press I can list the array under that folder

Thanks!
