README

Simple library to check that fiscal identifiers are valid according to Spanish legislation, and to generate valid fiscal identifiers.

Installation

composer require yivoff/nif-check

Usage

$checker = new \Yivoff\NifCheck\NifChecker();

// returns true if valid
$checker->verify($anyNif);

NIF Generator

An utility is provided to generate valid NIFs, which could be useful for testing purposes or similar scenarios.

$generator = new \Yivoff\NifCheck\Generator\RandomNif();

// Generates a valid DNI
$validDni = $generator->generateDni();
 
// Generates a valid NIE
$validNie = $generator->generateNie();
 
// Generates a valid CIF
$validCif = $generator->generateCif();
 
// Generates a valid NIF (randomly DNI, NIF, or CIF)
$validNif = $generator->generate();

Symfony Validator integration

The package provides a Symfony Validator attribute, which can simply be used like this:

use Yivoff\NifCheck\Validator\ValidNif;

class User
{
    #[ValidNif]
    public string $nif;
}

fakerphp/faker Integration

The package also includes a Faker Provider.

$faker = Faker\Factory::create();
$faker->addProvider(new \Yivoff\NifCheck\FakerProvider\NifProvider($faker, new \Yivoff\NifCheck\Generator\RandomNif()));

// now you can fake NIFs

$faker->spanishDni();
$faker->spanishNie();
$faker->spanishCif();
$faker->spanishNif();
