function dirList ($directory)
{

 
    $results = array();
    $handler = opendir($directory);
    while ($file = readdir($handler)) {
        if ($file != '.' && $file != '..')
            $results[] = $file;
    }


    closedir($handler);
    return $results;

}

$array = dirList(/path/to/howtos);
