Naturally sort a flat array without preserving original keys

Question

Is there any way for natsort() to not preserve keys?

$array = array(
    'IMG0.png',
    'img12.png',
    'img10.png',
    'img2.png',
    'img1.png',
    'IMG3.png'
);
natsort($array);

Result:

array (
  0 => 'IMG0.png',
  5 => 'IMG3.png',
  4 => 'img1.png',
  3 => 'img2.png',
  2 => 'img10.png',
  1 => 'img12.png',
)

But I want:

array (
  0 => 'IMG0.png',
  1 => 'img1.png',
  2 => 'img2.png',
  3 => 'IMG3.png',
  4 => 'img10.png',
  5 => 'img12.png',
)

Answer 1

array_values will effectively reindex any array passed to it with sequential integer keys. So you just need to do:

natsort($array);
$array = array_values($array);
