$dir_path = "/path/to/directory/";
$count = count(glob($dir_path . "*"));

if($count >= 1){
 echo $count;

} else {
 echo 0;
}

Where you want it to appear.

Just a little modified:

function count_files($dir_path = '', $what = '') {
    $count = count(glob($dir_path.'/*.'.$what.''));
    return echo 'There is '.($count > 1 
            ? '<b>'.$count.'</b> files' : ($count == 1 
            ? '<b>one</b> file' : '<b>no files</b>')).' in '.dirname($dir_path).'<br/>'.PHP_EOL;
}
//
count_files('downloads/images', 'jpg');
count_files('downloads/images', 'jpg|jpeg');
count_files('downloads/videos', '3gp');
count_files('downloads/videos', '3gp|mp4');
