Alpha

• Alpha()
• Alpha(string ...$additionalChars)

Validates whether the input contains only alphabetic characters. This is similar to Alnum, but it does not allow numbers.

v::alpha()->isValid('some name'); // false
v::alpha(' ')->isValid('some name'); // true
v::alpha()->isValid('Cedric-Fabian'); // false
v::alpha('-')->isValid('Cedric-Fabian'); // true
v::alpha('-', '\'')->isValid('\'s-Gravenhage'); // true

You can restrict case using the Lowercase and Uppercase rules.

v::alpha()->uppercase()->isValid('example'); // false
