for example we want to sort this

$users

array according to

"score"

value

$users = array(
    [
        'id' => 1, 
        'name' => 'vighac tipovichi', 
        'score' => 90
    ],
    [
        'id' => 2, 
        'name' => 'sxva tipson', 
        'score' => 100
    ],

);

__________________________________________ 1st method is using this custom function:

array_sort($users, 'score', SORT_DESC)

function array_sort($array, $on, $order=SORT_ASC){
    $new_array = array();
    $sortable_array = array();

    if (count($array) > 0) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                foreach ($v as $k2 => $v2) {
                    if ($k2 == $on) {
                        $sortable_array[$k] = $v2;
                    }
                }
            } else {
                $sortable_array[$k] = $v;
            }
        }


        switch ($order) {
            case SORT_ASC:
                asort($sortable_array);
            break;
            case SORT_DESC:
                arsort($sortable_array);
            break;
        }

        foreach ($sortable_array as $k => $v) {
            $new_array[$k] = $array[$k];
        }
    }
  return $new_array;
}

__________________________________________ 2nd method is by using

usort

built-in function which allows us to use "user defined" callback/function to sort array: 1.either by declaring another function dedicated to sort array as you wish

function custom_sort_users($a, $b) {
        if ($a['score'] == $b['score']) {
                return 0;
        }
        return ($a['score'] > $b['score']) ? -1 : 1;
}
usort($users, "custom_sort_users");

2.or using callback:

usort($users, function($a, $b){
    if ($a['score'] == $b['score']) {
            return 0;
    }
    return ($a['score'] > $b['score']) ? -1 : 1;
});
