How do you sort an array based on value

Question

array(3) { [0]=> int(1) [1]=> int(100) [2]=> int(6) }

I want to sort the following array in numerical order max - min.

Expected output:

array(3) { [0]=> int(100) [1]=> int(6) [2]=> int(1) }

However, when I use asort($arr, SORT_NUMERIC) or sort($arr, SORT_NUMERIC) I get this unexpected result:

array(3) { [0]=> int(6) [1]=> int(100) [2]=> int(1) }

Answer 1

PHP sort() has SORT_NATURAL flag.

It should be...

sort($array, SORT_NATURAL);
// or
rsort($array, SORT_NATURAL);

Tests:

$array = [1, 100, 6];

sort($array, SORT_NATURAL);

var_dump($array);

rsort($array, SORT_NATURAL);
var_dump($array);

array (size=3) 0 => int 1 1 => int 6 2 => int 100

array (size=3) 0 => int 100 1 => int 6 2 => int 1
