# No

- `v::no()`
- `v::no(boolean $locale)`

Validates if value is considered as "No".

```php
v::no()->validate('N'); // true
v::no()->validate('Nay'); // true
v::no()->validate('Nix'); // true
v::no()->validate('No'); // true
v::no()->validate('Nope'); // true
v::no()->validate('Not'); // true
```

This rule is case insensitive.

If `$locale` is TRUE, uses the value of [nl_langinfo()](http://php.net/nl_langinfo) with `NOEXPR` constant.
