# StringVal
- `StringVal()`
Validates whether the input can be used as a string.
```php
v::stringVal()->validate('6'); // true
v::stringVal()->validate('String'); // true
v::stringVal()->validate(1.0); // true
v::stringVal()->validate(42); // true
v::stringVal()->validate(false); // true
v::stringVal()->validate(true); // true
v::stringVal()->validate(new ClassWithToString()); // true if ClassWithToString implements `__toString`
```
