Sort multidimensional array by index

Question

Assuming we have the following array:

$edibles = [

    ['Apple', 250],
    ['Pear', 300],
    ['Cherry', 270],
    ['Tomato', 300],
    ['Carrot', 240],
    ['Potato', 170]

];

What would be the best way to sort those items by item[1]?

There are no array keys present which is why the google results didn't help me very much.

Thank you in advance!

Sure, if you're talking about 250, 300, 270, etc. the array key is `1` as you've stated. — AbraCadaver, Apr 12 '18 at 17:32

usort( $edibles, function ( $a, $b ) {
  return $a[1] - $b[1];
} );

You can extract the values from index 1, sort that and then sort the original on that using array_multisort():

array_multisort(array_column($edibles, 1), SORT_ASC, $edibles);
