# Max

- `Max(Rule $rule)`

Validates the maximum value of the input against a given rule.

```php
v::max(v::equals(30))->isValid([10, 20, 30]); // true

v::max(v::between('e', 'g'))->isValid(['b', 'd', 'f']); // true

v::max(v::greaterThan(new DateTime('today')))
        ->isValid([new DateTime('yesterday'), new DateTime('tomorrow')]); // true

v::max(v::greaterThan(15))->isValid([4, 8, 12]); // false
```

## Note

This rule uses [Length](Length.md) with [GreaterThan][GreaterThan.md] internally. If an input has no items, the validation will fail.
