Sorting Array

Greetings all,

I have a script that creates an array from a folder of images.

// Create Array
$files = array();
if( is_dir( $thumbs_dir ) ) {
  if( $handle = opendir( $thumbs_dir ) ) {
    while( ( $file = readdir( $handle ) ) !== false ) {
      if( $file != "." && $file != ".." ) {
        array_push( $files, $file );
      }
    }
    closedir( $handle );
  }
}

If I echo this array out into a table or what have you it lists them in a strange way.

......and so on up to 19

As you can see the array comes out in, well, a numeric order but a weird one. Instead of loading 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, it loads like above 1, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 21, 22.....

How can I go about sorting this so that it comes out how one would count normally? Preferably in reverse order, counting down would be better.

I tried:

sort( $files, SORT_NUMERIC );

But that got really messy and threw the order all over the place.

Best Regards,
