Introduction

This package implements the GB/T 3304-1991 standard "Names of nationalities of China in romanization with codes" as a type-safe PHP 8.1+ enum. It provides both numeric (01-56) and two-letter (HA-JN) codes for all 56 officially recognized Chinese ethnic groups, with convenient integration interfaces for modern PHP applications.

Overview

GB/T 3304-1991 is a Chinese national standard that defines the romanization and coding system for Chinese ethnic groups. This package provides a modern PHP implementation using enums, making it easy to work with Chinese nationality data in a type-safe manner.

Features

• Complete Coverage: All 56 officially recognized Chinese ethnic groups
• Dual Coding System: Both numeric codes (01-56) and two-letter codes (HA-JN)
• Type Safety: Modern PHP 8.1+ enum implementation
• Easy Integration: Implements Labelable, Itemable, and Selectable interfaces
• Clean API: Simple methods for code, label, and mapping conversion
• Well Tested: Comprehensive PHPUnit test suite with 100% coverage
• Standards Compliant: Follows GB/T 3304-1991 specification exactly

Installation

Requirements:

• PHP >= 8.1
• Composer
• Dependency: tourze/enum-extra ~0.1.0

Install via Composer:

composer require tourze/gb-t-3304

Quick Start

use Tourze\GBT3304\Nationality;

// Get numeric code
$code = Nationality::Han->value; // "01"

// Get Chinese label
$label = Nationality::Han->getLabel(); // "汉族"

// Get two-letter code
$alphaCode = Nationality::Han->toCode(); // "HA"

Advanced Usage

Getting All Nationalities

// Get all nationality options for forms/selects
$options = Nationality::getSelectOptions();
// Returns: ['01' => '汉族', '02' => '蒙古族', ...]

// Get as items for API responses
$items = Nationality::getItems();
// Returns: [['value' => '01', 'label' => '汉族'], ...]

Finding by Code

// From numeric code
$nationality = Nationality::from('01'); // Han

// From alpha code (you'll need to implement this if needed)
$han = array_search('HA', array_map(fn($n) => $n->toCode(), Nationality::cases()));

Integration with Forms

// Symfony forms
$builder->add('nationality', ChoiceType::class, [
    'choices' => Nationality::getSelectOptions(),
]);

// Laravel
Form::select('nationality', Nationality::getSelectOptions());
