## 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](https://semver.org/). 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](./UPGRADING.md) file in the root of this project.

[![Daily country spec update](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-country.yml/badge.svg)](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-country.yml)

> :mortar_board: **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)

> :mortar_board: **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.

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

CountryCallingCode::from(1);                    // CountryCallingCode::Integrated_numbering_plan
CountryCallingCode::from(31);                   // CountryCallingCode::Netherlands_Kingdom_of_the
CountryCallingCode::from(31)->value;            // 31
CountryCallingCode::from(31)->name;             // 'Netherlands_Kingdom_of_the'
CountryCallingCode::Netherlands_Kingdom_of_the; // CountryCallingCode::Netherlands_Kingdom_of_the

CountryCallingCode::from(31)->getCountriesAlpha2(); // [CountryAlpha2::Netherlands]

## Currency (ISO4217)

[![Daily currency spec update](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-currency.yml/badge.svg)](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-currency.yml)

> :mortar_board: **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.

HttpMethod::from('POST');        // HttpMethod::Post
HttpMethod::from('POST')->value; // 'POST'
HttpMethod::from('POST')->name;  // Post

function foo(HttpMethod $httpMethod): void {} // Use spec as typehint to enforce valid value
```

## HTTP Status Codes

[![Daily HTTP Status code spec update](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-http-status-codes.yml/badge.svg)](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-http-status-codes.yml)

### At a glance

```php
use PrinsFrank\Standards\Http\HttpStatusCode;

HttpStatusCode::from(404);       // HttpStatusCode::Not_Found
HttpStatusCode::from(404)->value; // 404
HttpStatusCode::from(404)->name;  // Not_Found
HttpStatusCode::Not_Found;       // HttpStatusCode::Not_Found

function foo(HttpStatusCode $httpStatusCode): void {} // Use spec as typehint to enforce valid value
```

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.

## International Call Prefixes (ITU-T E.164)

Different countries have different international call prefixes. This is a spec extracted from ITU-T E.164 listing all possible international call prefixes.

use PrinsFrank\Standards\Country\CountryAlpha2;
use PrinsFrank\Standards\Country\CountryAlpha3;
use PrinsFrank\Standards\Country\CountryName;

## Language (ISO639)

[![Daily language spec update](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-language.yml/badge.svg)](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-language.yml)

> :mortar_board: **Language codes are always in lowercase to avoid confusion with country codes.**

> :mortar_board: **The alpha2 specification has 184 languages, the alpha3 Bibliographic/Terminology specification has 486 languages and the alpha3 Extensive specification has 7908 languages.**

> :mortar_board: **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.

ScriptAlias::from('Latin');                          // ScriptAlias::latin
ScriptAlias::from('Latin')->value;                   // 'Latin'
ScriptAlias::from('Latin')->name;                    // 'Latin'
ScriptAlias::from('Latin')->toScriptCode();          // ScriptCode::Latin
ScriptAlias::from('Latin')->toScriptName();          // ScriptName::Latin
ScriptAlias::from('Latin')->toScriptNumber();        // ScriptNumber::Latin
ScriptAlias::Latin;                                  // ScriptAlias::Latin
ScriptAlias::from('Latin')->isSupportedByPHPRegex(); // true

ScriptAlias::allForString('еюeuеюευ');               // [ScriptAlias::Cyrillic, ScriptAlias::Greek, ScriptAlias::Latin]
ScriptAlias::hasMultipleForString('еюeuеюευ');       // true
ScriptAlias::mostCommonInString('еюeuеюευ');         // ScriptAlias::Cyrillic

function foo(ScriptAlias $scriptAlias): void {} // Use spec as typehint to enforce valid value
```

PHP has regex support for detecting scripts using the following notation:

Match any Arabic character
```regexp
\p{Arabic}
```

Match any NON-Arabic character
```regexp
\P{Arabic}
```

Not all scripts are supported by PHP regular expressions. An exhaustive list can be found in the [PHP documentation for Unicode character properties](https://www.php.net/manual/en/regexp.reference.unicode.php). For convenience, the information on that page is parsed daily and supplied in this package using the `isSupportedByPHPRegex` method and `SupportedByPHPRegex` attribute which is the underlying information used by the `isSupportedByPHPRegex` method.

### ScriptCode

## TLDs

[![Daily TLD spec update](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-tld.yml/badge.svg)](https://github.com/PrinsFrank/standards/actions/workflows/update-spec-tld.yml)

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.

### CountryCodeTLD

Where a TLD is marked as unmanaged by IANA it is marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\CountryCodeTLD;

CountryCodeTLD::from('nl');                      // CountryCodeTLD::nl
CountryCodeTLD::nl;                              // CountryCodeTLD::nl
CountryCodeTLD::from('nl')->value;               // 'nl'
CountryCodeTLD::from('nl')->name;                // 'nl'
CountryCodeTLD::from('nl')->isAssigned();        // true
CountryCodeTLD::from('nl')->getCountryAlpha2();  // CountryAlpha2::Netherlands
CountryCodeTLD::from('nl')->getCountryAlpha3();  // CountryAlpha3::Netherlands
CountryCodeTLD::from('nl')->getCountryNumeric(); // CountryNumeric::Netherlands

function foo(CountryCodeTLD $countryCodeTLD): void {} // Use spec as typehint to enforce valid value
```

### GenericRestrictedTLD

Where a TLD is marked as unmanaged by IANA it is marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\GenericRestrictedTLD;

GenericRestrictedTLD::from('name');                // GenericRestrictedTLD::name
GenericRestrictedTLD::name;                        // GenericRestrictedTLD::name
GenericRestrictedTLD::from('name')->value;         // 'name'
GenericRestrictedTLD::from('name')->name;          // 'name'
GenericRestrictedTLD::from('name')->isAssigned();  // true

function foo(GenericRestrictedTLD $genericRestrictedTLD): void {} // Use spec as typehint to enforce valid value
```

### GenericTLD

Where a TLD is marked as unmanaged by IANA it is marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\GenericTLD;

GenericTLD::from('aaa');                // GenericTLD::aaa
GenericTLD::aaa;                        // GenericTLD::aaa
GenericTLD::from('aaa')->value;         // 'aaa'
GenericTLD::from('aaa')->name;          // 'aaa'
GenericTLD::from('aaa')->isAssigned();  // true

function foo(GenericTLD $genericTLD): void {} // Use spec as typehint to enforce valid value
```

### InfrastructureTLD

Where a TLD is marked as unmanaged by IANA it is marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\InfrastructureTLD;

InfrastructureTLD::from('arpa');                // InfrastructureTLD::arpa
InfrastructureTLD::arpa;                        // InfrastructureTLD::arpa
InfrastructureTLD::from('arpa')->value;         // 'arpa'
InfrastructureTLD::from('arpa')->name;          // 'arpa'
InfrastructureTLD::from('arpa')->isAssigned();  // true

function foo(InfrastructureTLD $infrastructureTLD): void {} // Use spec as typehint to enforce valid value
```

### SponsoredTLD

Where a TLD is marked as unmanaged by IANA it is marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\SponsoredTLD;

SponsoredTLD::from('aero');                // SponsoredTLD::aero
SponsoredTLD::aero;                        // SponsoredTLD::aero
SponsoredTLD::from('aero')->value;         // 'aero'
SponsoredTLD::from('aero')->name;          // 'aero'
SponsoredTLD::from('aero')->isAssigned();  // true

function foo(SponsoredTLD $sponsoredTLD): void {} // Use spec as typehint to enforce valid value
```

### TestTLD

All Test TLDs are always unmanaged and are thus never marked as deprecated.

```php
use PrinsFrank\Standards\TopLevelDomain\TestTLD;

TestTLD::from('テスト');               // TestTLD::tesuto_katakana
TestTLD::tesuto_katakana;             // TestTLD::tesuto_katakana
TestTLD::from('テスト')->value;        // 'テスト'
TestTLD::from('テスト')->name;         // 'tesuto_katakana'
TestTLD::from('テスト')->isAssigned(); // false

function foo(TestTLD $testTLD): void {} // Use spec as typehint to enforce valid value
```
