README

Finnish Social Security number validator.

This simple class validates social security numbers and provides methods for checking birthdate, age and gender based on the 'hetu'.

Requirements

• PHP >= 8.0

Installation

The recommended way is to install the lib through Composer.

composer require devsmo/php-hetu

Or you can add this to your composer.json

{
    "require": {
        "devsmo/php-hetu": "^1.0"
    }
}

Usage

The hetu class creates an immutable value object. You can initialize the object in two ways:

<?php

$hetu = Devsmo\Hetu::create('041281-981T');

if ( $hetu ) {
	echo "It's valid";
}
else {
	echo "It's not valid...";
}

Or if you want to catch possible errors:

<?php

try {
	$hetu = new Devsmo\Hetu('041281-981T');
}
catch (\InvalidArgumentException $e){
	$msg = $e->getMessage();
}

The class has three methods:

<?php
$age = $hetu->getAge(); // 35

$date_of_birth = $hetu->getDateStr(); // 1981-12-04

$gender = $hetu->getGender(); // male
