A collection of standards as PHP Enums

Daily updated from their sources, whether it is ISO or IANA directly, or a maintaining party like the SIX Group or the US Library of Congress.

This package is actively maintained. Sponsorship helps support ongoing maintenance and review of upstream changes.

Setup

Note Make sure you are running PHP 8.1 or higher to use this package

To start right away, run the following command in your composer project;

composer require prinsfrank/standards

Or for development only;

composer require prinsfrank/standards --dev

💖 Sponsorship

This package is regularly updated as upstream standards change. Keeping it reliable and consistent takes ongoing effort. Even though most of the standards in this package are automatically checked with upstream sources, these changes still need to be manually reviewed. When sources update the way they present their data, the parsing scripts also need to be updated.

If you depend on this package and want to support its maintenance, please consider sponsoring me. I'll continue maintaining and releasing updates regardless, but sponsorships help cover the time it takes to review changes and keep everything accurate.

How this package works

This package implements a bunch of specs as PHP Enums, so you can typehint them in methods. Currently, all specs are implemented as backed enums. That means that besides a name, they have also an internal 'value', either as an integer or a string.

In the Country, Currency and language specifications, there is also a relation between different enums. For example, the Alpha2 country code 'NL' is related to the Alpha3 'NLD', the numeric value '528' and the name 'Netherlands (the)'. Internally, these specs rely on the fact that the keys for these values are identical, so it is possible to convert between these.

Entities and their relations

All specifications in this package are closely related, except for the Http status code and methods. Not all relations are bidirectional though. For example, a language tag is build up of a language and optionally a country, but only a country cannot be converted to a language tag.

Below you can find an overview of all the relationships between specifications.

Upgrading

This package adheres to semver. This means that there are no breaking changes between minor releases (for example from 1.1 to 1.2), but that breaking changes are released as a major release (for example from 1.x to 2.x). To read about upgrading from one major release to the next, please refer to the UPGRADING.md file in the root of this project.

Country (ISO3166-1)

👁 Daily country spec update

🎓 Alpha2/3 country codes are always UPPERCASE to avoid confusion with language codes. It is recommended to use Alpha2/Alpha3 codes when exposing the specification in APIs

At a glance

All the Alpha2, Alpha3, Numeric and Name values have a corresponding enum in the other country enums. These can be converted using their corresponding methods (toAlpha2, toAlpha3 etc...).

Country group membership can be checked by calling the isMemberOf method, supplying the FQN of a class that implements the GroupInterface. Several country groups are available: BRICS, EEA, EFTA etc. Countries can also have subdivisions, which can be of several types: countries, provinces, etc.

Country Calling Codes (ITU-T E.164)

🎓 Country calling codes can be anywhere from 1 to 3 digits, and can span several countries. There are no leading zeros in this specification.

At a glance

Country calling codes are quite straight forward. One country can have multiple country calling codes though, And one country calling code can span multiple countries. That's why the forCountry and getCountriesAlpha2 both return an array of country calling codes/countries and not a single item.

use PrinsFrank\Standards\Country\CountryAlpha2;
use PrinsFrank\Standards\CountryCallingCode\CountryCallingCode;

CountryCallingCode::from(1); // CountryCallingCode::Integrated_numbering_plan

Currency (ISO4217)

👁 Daily currency spec update

🎓 Alpha3 codes are uppercase. When communicating or storing currencies, it is recommended to do so using the Alpha3 or Numeric representation.

At a glance

All the Alpha3, Numeric and Name values have a corresponding enum in the other currency enums. These can be converted using their corresponding methods (toCurrencyAlpha3, etc...). A fourth enum is available that maps all currencies to a currency symbol, that can be accessed by calling the 'getSymbol' method.

There can be status codes that are temporarily assigned. Those are marked with the TemporaryAssignment attribute. To check if a specific case is temporarily assigned, you can use the isTemporaryAssignment method which returns a boolean, or getTemporaryAssignmentExpiresAt which returns a DateTimeImmutable or null.

Language (ISO639)

👁 Daily language spec update
👁 Daily Language Extensive update

🎓 Language codes are always in lowercase to avoid confusion with country codes.

🎓 The alpha2 specification has 184 languages, the alpha3 Bibliographic/Terminology specification has 486 languages and the alpha3 Extensive specification has 7908 languages.

🎓 If you have to choose between the alpha3 Bibliographic and Terminology specification, the Terminology specification is more widely used.

At a glance

There are four language code specifications:

• 184 Language Alpha2 (ISO 639-1)
• 486 Language Alpha3 Bibliographic (ISO 639-2)
• 486 Language Alpha3 Terminology (ISO 639-2)
• 7908 Language Alpha3 Extensive (ISO 639-3)

As you see, the Bibliographic and Terminology specifications have an identical number of languages, so there is a one-to-one relation between these.

TLDs

👁 Daily TLD spec update

There are currently 6 types of Top Level Domains:

• CountryCode
• GenericRestricted
• Generic
• Infrastructure
• Sponsored
• Test

Most of these specification have several TLDs that are 'unmanaged' and are thus not currently available. Those are marked as deprecated, but are kept in the specification. There is one exception: All Test TLDs are always unmanaged and are thus never marked as deprecated.
