README

This library provides tools for validating, parsing, and generating Kazakhstan Individual Identification Numbers (IIN).

About Kazakhstan IIN

In Kazakhstan, the Individual Identification Number (IIN) is a unique identifier assigned to individuals. The IIN is composed of 12 digits, where each digit represents specific information about the individual, such as the date of birth, gender, and a unique identifier for individuals born on the same date. More detailed information about the structure and purpose of the IIN can be found here.

Features

• Validate Kazakhstan IINs
• Parse Kazakhstan IINs to extract useful information
• Generate valid Kazakhstan IINs
• Exception handling for various validation errors

Installation

You can install the package via composer:

composer require vonlab/kz-iin

Usage

Validating an IIN

To validate an IIN, use the IinValidator class.

With Exception Handling

<?php

use VonLab\KzIin\IinParser;
use VonLab\KzIin\IinValidator;

$validator = new IinValidator(new IinParser());

try {
    if ($validator->validate('your-iin-here')) {
        echo "IIN is valid.";
    }
} catch (\Exception $e) {
    echo "Validation failed: " . $e->getMessage();
}

Without Exception Handling

use VonLab\KzIin\IinParser;
use VonLab\KzIin\IinValidator;

$validator = new IinValidator(new IinParser());

if ($validator->isValid('your-iin-here')) {
    echo "IIN is valid.";
} else {
    echo "Validation failed: " . $validator->getError();
}

IIN Generation

To generate an IIN, use the IinGenerator class.

<?php

use VonLab\KzIin\IinGenerator;
use VonLab\KzIin\Enums\GenderEnum;
use VonLab\KzIin\Data\BirthDate;

// Generate an IIN with random birthdate and gender
$generator = new IinGenerator();
$iin = $generator->generate();
echo "Generated IIN: $iin";

// Generate an IIN with specific birthdate and gender
$birthDate = new BirthDate(1990, 1, 1);
$gender = GenderEnum::Male;
$iin = $generator->generate($birthDate, $gender);
echo "Generated IIN: $iin";

Parsing an IIN

To parse an IIN, use the IinParser class.

<?php

use VonLab\KzIin\IinParser;
use VonLab\KzIin\Utils\DateConverter;
use VonLab\KzIin\Exceptions\InvalidIinFormatException;

$parser = new IinParser();

try {
    $iinData = $parser->parse('your-iin-here');
    
    echo "Birth Date: " . DateConverter::toDateString($iinData->birthDate);
    echo "Year of birth: " . $iinData->birthDate->year;
    echo "Month of birth: " . $iinData->birthDate->month;
    echo "Day of birth: " . $iinData->birthDate->day;
    echo "Gender: " . $iinData->gender->value;
    echo "Century Gender Digit: " . $iinData->centuryGenderDigit;
    echo "Registration Number: " . $iinData->registrationNumber;
    echo "Control Digit: " . $iinData->controlDigit;
} catch (InvalidIinFormatException $e) {
    echo "Invalid IIN format: " . $e->getMessage();
}

Additional Information

Exception Classes

The library provides specific exception classes to handle various validation errors:

• InvalidIinLengthException
• InvalidIinCharacterException
• InvalidBirthDateException
• InvalidCenturyGenderDigitException
• InvalidControlDigitException
• InvalidIinFormatException

Utility Classes

The library includes utility classes for internal calculations and date handling:

• IinHelper: Contains methods for checksum calculations and century/gender digit extraction.
• DateConverter: Utility class for date format conversions.

Docker Support

A minimal docker-compose.yml is included for setting up the development environment.

Testing

The library includes a comprehensive set of unit tests. To run the tests, use the following command:

composer test
