# Value

`Value` checks a value that was received, as from a form or a request.

## isBlank

`Value::isBlank($value)` tells if nothing was received: it is `true` for `null`, `''` and `[]`, and `false` for any other value.

```php
use Derafu\Support\Value;

Value::isBlank(null);      // true
Value::isBlank('');        // true
Value::isBlank([]);        // true

Value::isBlank(0);         // false
Value::isBlank('0');       // false
Value::isBlank(false);     // false
Value::isBlank('  ');      // false
```

It is not the `empty()` of PHP: `0`, `'0'` and `false` are values, and a text of spaces has characters.
