 Use variadics "AbstractFilterRule" rule 
Since the library doesn't need to give support to version 5.4 or less of
PHP using variadics in the constructor of "AbstractFilterRule" seems
better than doing the whole validation.

This commit will also apply the contribution guidelines to
"AbstractFilterRule" and use a better naming for it.

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()->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 and Uppercase rules.

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