I want to scan the last folder in a directory and display the images in it

Question

So far ive gotten this down but it displays the contents for all the folders not just the last one. Ive tried using end(); on the list but that didnt work.

    function listFolderFiles($dir){
    $ffs = scandir($dir);
    $i = 0;
    $list = array();
    foreach ( $ffs as $ff ){
        if ( $ff != '.' && $ff != '..' ){
            if ( strlen($ff)>=5 ) {

                    $list[] = $ff;
                    //echo dirname($ff) . $ff . "<br/>";
                    echo $dir.'/'.$ff.'<br/>';

            }       
            if( is_dir($dir.'/'.$ff) ) 
                    listFolderFiles ($dir.'/'.$ff);
        }
    }
    return $list;
}

$files = array();
$files = listFolderFiles(dirname(__FILE__));

lets say for instance i have a folder and within it i have folders named as such

• 02-08-2016
• 02-09-2016
• 02-10-2016
• 02-11-2016
• 02-12-2016

I want it to always pick the last folder, and display its contents which are images.
