nif-validator

A modern PHP 7.0+ Spanish NIF (Número de Indentifación Fiscal) validator.

Why another NIF validator?

Other NIF validators we saw either had really obscure code or just implemented a validator for the DNI/NIE, not the CIF.

Usage

<?php

use NifValidator\NifValidator;

//CIF
assert(NifValidator::isValid('B65410011'));
//DNI
assert(NifValidator::isValid('93471790C'));
//NIE
assert(NifValidator::isValid('X5102754C'));

This validator does not strip or uppercase any character, it's your responsibility to previously filter the input.
