JMBG

PHP class used to extract data from ex Yugoslavian unique master citizen numbers.

Introduction

JMBG (jedinstveni matični broj građana) or unique master citizen numbers is a 13 characters long number assigned to all newborns in ex Yugoslavian countries. It seems random but it isn't. It holds following data:

• date of birth
• state of birth
• place of birth (region/city)
• gender
• validation checksum

This PHP class can be used to extract this data from JMBG numbers. It uses PSR-4 autoloading standard.

Intallation

Install using composer with:

composer require avram/jmbg

Or manually by cloning this repository:

git clone https://github.com/avramovic/JMBG.git

Usage

<?php
require 'vendor/autoload.php'

use Avram\JMBG\JMBG;
$jmbg = new JMBG('1905983710332');
$data = $jmbg->getInfo();

var_dump($data);

You should get output like this:

Array
(
    [jmbg] => 1905983710332
    [valid] => true
    [gender] => male
    [country] => Serbia
    [region] => Belgrade
    [birth_date] => 1983-05-19
    [birth_timestamp] => 422143200
    [age] => 32
)

Inspect the source code to see what methods are available in this class. Basically for every array element in the output above you have separate method.

Note

I've heard there are JMBGs issued with wrong checksum, so if that is true, it renders isValid() method useless. However, it is not a code issue, it's a bureaucracy issue. Most JMBGs are issued with a valid checksum.
