ulabox/nif-validator

Yet another(?) PHP implementation of the spanish NIF validator

nif-validator

, _(*1)

A modern PHP 7.0+ Spanish NIF (Número de Indentifación Fiscal) validator., _(*2)

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., _(*3)

Installation

Using Composer:, _(*4)

composer require ulabox/nif-validator

Usage

<?php

use NifValidator\NifValidator;

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

Starting from version 1.1.x you can also separetely validate personal and entity nifs, _(*5)

<?php

use NifValidator\NifValidator;

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

Starting from version 1.2.x you can also separetely validate individual nif types, _(*6)

```php <?php, <sub>(*7)</sub>

use NifValidator\NifValidator;, <sub>(*8)</sub>

//CIF assert(NifValidator::isValidCif('B65410011')); //DNI assert(NifValidator::isValidDni('93471790C')); //NIE assert(NifValidator::isValidNie('X5102754C'));, <sub>(*9)</sub>

This validator does not strip or uppercase any character, it's your responsibility to previously filter the input., <sub>(*10)</sub>
