Sorted

• Sorted(string $direction)

Validates whether the input is sorted in a certain order or not.

v::sorted('ASC')->isValid([1, 2, 3]); // true
v::sorted('ASC')->isValid('ABC'); // true
v::sorted('DESC')->isValid([3, 2, 1]); // true
v::sorted('ASC')->isValid([]); // true
v::sorted('ASC')->isValid([1]); // true

You can also combine Call to create custom validations:

v::call(
        static function (array $input): array {
            return array_column($input, 'key');
        },
        v::sorted('ASC')
    )->isValid([
        ['key' => 1],
        ['key' => 5],
        ['key' => 9],
    ]); // true

v::call('strval', v::sorted('DESC'))->isValid(4321); // true

v::call('iterator_to_array', v::sorted())->isValid(new ArrayIterator([1, 7, 4])); // false
