README

Simple package to assist you in converting/mapping ISO 3166-1 Alpha-2, Alpha-3, and Numeric Country Codes.

Installation

Install the latest version with

$ composer require graftak/country-code-helper

Usage

Include these two classes:

use Graftak\CountryCodeHelper;
use Graftak\CountryCodeHelper\CountryCodes;

Then, in your code, just use the static method map:

CountryCodeHelper::map($value, $toType);

The first parameter $value is the country code (string) you want to map from. For example:

• 'NL' (2-letter country code for The Netherlands)
• 'BRA' (3-letter country code for Brazil)
• '024' (numeric country code for Angola)

The second parameter $toType is the type you want to map to. These types are supported:

CountryCodes::ALPHA_2
CountryCodes::ALPHA_3
CountryCodes::NUMERIC
CountryCodes::SHORT_NAME_ENGLISH
CountryCodes::SHORT_NAME_FRENCH

Optionally you can supply the third parameter to explicitly define the type of the given $value (you can use any of the constants above).

Examples

<?php

use Graftak\CountryCodeHelper;
use Graftak\CountryCodeHelper\CountryCodes;

// Example 1 (The Netherlands): Two-letter to three-letter code.
print CountryCodeHelper::map('NL', CountryCodes::ALPHA_3);
// Output: 'NLD'

// Example 2 (Philippines): Numeric to two-letter code.
print CountryCodeHelper::map(608, CountryCodes::ALPHA_2);
// Output: 'PH'

// Example 3 (Virgin Islands): Two-letter to English name.
print CountryCodeHelper::map('VG', CountryCodes::SHORT_NAME_ENGLISH);
// Output: 'Virgin Islands (British)'

Country Codes - ISO 3166

What is ISO 3166? ISO 3166 is the International Standard for country codes and codes for their subdivisions.

The purpose of ISO 3166 is to define internationally recognised codes of letters and/or numbers that we can use when we refer to countries and subdivisions. However, it does not define the names of countries – this information comes from United Nations sources (Terminology Bulletin Country Names and the Country and Region Codes for Statistical Use maintained by the United Nations Statistics Divisions).

Using codes saves time and avoids errors as instead of using a country's name (which will change depending on the language being used) we can use a combination of letters and/or numbers that are understood all over the world.

For example, all national postal organizations throughout the world exchange international mail in containers identified with the relevant country code. Internet domain name systems use the codes to define top level domain names such as '.fr' for France, '.au' for Australia. In addition, in machine readable passports, the codes are used to determine the nationality of the user and when we send money from one bank to another the country codes are a way to identify where the bank is based.
