What potential issues can arise when using natsort() and reset() functions in PHP?

When using natsort() and reset() functions in PHP, a potential issue that can arise is that the array keys may not be reset after sorting the array with natsort(). This can lead to unexpected behavior when trying to access elements by their keys. To solve this issue, you can use array_values() function after sorting the array to re-index the array keys.

$array = ['img1.png', 'img10.png', 'img2.png'];
natsort($array);
$array = array_values($array);
reset($array);
