# Alpha
|
|
|
|
- `Alpha()`
|
|
- `Alpha(string ...$additionalChars)`
|
|
|
|
Validates whether the input contains only alphabetic characters. This is similar
|
|
to [Alnum](Alnum.md), but it does not allow numbers.
|
|
|
|
```php
|
|
v::alpha()->validate('some name'); // false
|
|
v::alpha(' ')->validate('some name'); // true
|
|
v::alpha()->validate('Cedric-Fabian'); // false
|
|
v::alpha('-')->validate('Cedric-Fabian'); // true
|
|
v::alpha('-', '\'')->validate('\'s-Gravenhage'); // true
|
|
```
|
|
|
|
You can restrict case using the [Lowercase](Lowercase.md) and
|
|
[Uppercase](Uppercase.md) rules.
|
|
|
|
```php
|
|
v::alpha()->uppercase()->validate('example'); // false
|
|
```
