# NotBlank

- `NotBlank()`

Validates if the given input is not a blank value (`null`, zeros, empty strings
or empty arrays, recursively).

```php
v::notBlank()->isValid(null); // false
v::notBlank()->isValid(''); // false
v::notBlank()->isValid([]); // false
v::notBlank()->isValid(' '); // false
v::notBlank()->isValid(0); // false
v::notBlank()->isValid('0'); // false
v::notBlank()->isValid(0); // false
v::notBlank()->isValid('0.0'); // false
v::notBlank()->isValid(false); // false
v::notBlank()->isValid(['']); // false
v::notBlank()->isValid([' ']); // false
v::notBlank()->isValid([0]); // false
v::notBlank()->isValid(['0']); // false
v::notBlank()->isValid([false]); // false
v::notBlank()->isValid([[''], [0]]); // false
v::notBlank()->isValid(new stdClass()); // false
```

It's similar to [NotEmpty](NotEmpty.md) but it's way more strict.
