Geographer is a PHP library that knows how any country, state or city is called in any language. Documentation on the official website

Includes integrations with: Laravel 5, Lumen 5

Geographer

Dependencies

  • PHP >= 5.5

Installation via Composer

To install simply run:

$ composer require menarasolutions/geographer

Or add it to composer.json manually:

{
    "require": {
        "menarasolutions/geographer": "~0.3"
    }
}

This, main package is shipped with English language so add extra dependencies for your other languages, eg.:

$ composer require menarasolutions/geographer-es

Usage

use MenaraSolutions\Geographer\Earth;
use MenaraSolutions\Geographer\Country;

// Default entry point is our beautiful planet
$earth = new Earth();

// Give me a list of all countries please
$earth->getCountries()->toArray();

// Oh, but please try to use short versions, eg. USA instead of United States of America
$earth->getCountries()->useShortNames()->toArray();

// Now please give me all states of Thailand
$thailand = $earth->getCountries()->findOne(['code' => 'TH']); // You can call find on collection
$thailand = $earth->findOne(['code' => 'TH']); // Or right away on division
$thailand = $earth->findOneByCode('TH'); // Alternative shorter syntax
$thailand = Country::build('TH'); // You can build a country object directly, too
$thailand->getStates()->toArray();

// Oh, but I want them in Russian
$thailand->getStates()->setLocale('ru')->toArray();

// Oh, but I want them inflicted to 'in' form (eg. 'in Spain')
$thailand->getStates()->setLocale('ru')->inflict('in')->toArray();

// Or if you prefer constants for the sake of IDE auto-complete
$thailand->getStates()->setLocale(TranslationAgency::LANG_RUSSIAN)->inflict(TranslationAgency::FORM_IN)->toArray();

// What's the capital and do you have a geonames ID for that? Or maybe latitude and longitude?
$capital = $thailand->getCapital();
$capital->getGeonamesCode();
$capital->getLatitude();
$capital->getLongitude();

Collections

Arrays of administrative divisions (countries, states or cities) are returned as collections – a modern way of implementing arrays. Some of the available methods are:

$states->sortBy('name'); // States will be sorted by name
$states->setLocale('ru')->sortBy('name'); // States will be sorted by Russian translations/names
$states->find(['code' => 472039]); // Find 1+ divisions that match specified parameters 
$states->findOne(['code' => 472039]); // Return the first match only
$states->findOneByCode(472039); // Convenience magic method
$states->toArray(); // Return a flat array of states
$states->pluck('name'); // Return a flat array of state names

Common methods on division objects

All objects can do the following:

$object->toArray(); // Return a flat array with all data
$object->parent(); // Return a parent (city returns a state, state returns a country)
$object->getCode(); // Get default unique ID
$object->getShortName(); // Get short (colloquial) name of the object
$object->getLongName(); // Get longer name
$object->getCodes(); // Get a plain array of all available unique codes

You can access information in a number of ways, do whatever you are comfortable with:

$object->getName(); // Get object's name (inflicted and shortened when necessary)
$object->name; // Same effect
$object['name']; // Same effect
$object->toArray()['name']; // Same effect again

Subdivision standards

By default, we will use ISO-3166-1 country and ISO 3166-2 state classification. Therefore, countries or states that don't have ISO codes are not visible by default. Please note that FIPS 10-4 is a deprecated (abandoned) standard. It's better not to rely on it – new states and/or countries won't appear in FIPS.

You can change subdivision standard with setStandard method:

$country->setStandard(DefaultManager::STANDARD_ISO); // ISO subdivisions
$country->setStandard(DefaultManager::STANDARD_FIPS); // FIPS 10-4 subdivisions
$country->setStandard(DefaultManager::STANDARD_GEONAMES); // Geonames subdivisions

This will affect getStates() and getCountries() output.

Earth API

Earth object got the following convenience methods:

$earth->getAfrica(); // Get a collection of African countries
$earth->getEurope(); // Get a collection of European countries
$earth->getNorthAmerica(); // You can guess
$earth->getSouthAmerica(); 
$earth->getAsia();
$earth->getOceania();

$earth->getCountries(); // A collection of all countries
$earth->withoutMicro(); // Only countries that have population of at least 100,000

By default, we will use ISO 3166-1 country classification.

Country API

Country objects got the following encapsulated data:

$country->getCode(); //ISO 3166-1 alpha-2 (2 character) code
$country->getCode3(); // ISO 3166-1 alpha-3
$country->getNumericCode(); // ISO 3166-1 numeric code
$country->getGeonamesCode(); // Geonames ID
$country->getFipsCode(); // FIPS code
$country->getArea(); // Area in square kilometers
$country->getCurrencyCode(); // National currency, eg. USD
$country->getPhonePrefix(); // Phone code, eg. 7 for Russia
$country->getPopulation(); // Population
$country->getLanguage(); // Country's first official language

$country->getStates(); // A collection of all states
Country::build('TH'); // Build a country object based on ISO code

Geonames, ISO 3166-1 alpha-2, alpha-3 and numeric codes are four viable options to reference country in your data store.

State API

At this moment Geographer only keeps cities with population above 50,000 for the sake of performance.

$state->getCode(); // Get default code (currently Geonames)
$state->getIsoCode(); // Get ISO 3166-2 code  
$state->getFipsCode(); // Get FIPS code
$state->getGeonamesCode(); // Get Geonames code

$state->getCities(); // A collection of all cities
$state = State::build($id); // Instantiate a state directly, based on $id provided (Geonames or ISO)

Geonames, ISO 3166-2 and FIPS are all unique codes so all three can be used to reference states in your data store.

City API

$city->getCode(); // This is always a Geonames code for now
$city = City::build($id); // Instantiate a city directly, based on $id provided (Geonames) 
$city->getLatitude(); // City's latitude
$city->getLongitude(); // City's longitude
$city->getPopulation(); // Population

Geonames ID is currently the only viable option to reference a city in your data store.

Integrations with frameworks

Official Laravel package

Current coverage: subdivisions

Type ISO 3166 FIPS Geonames GENC
Countries 100% Coming soon 100% TBC
States 100% Coming soon 100% TBC

Subdivision data is kept in a separate repo - geographer-data so that it may be reused by different language SDKs.

Current coverage: translations

By default Geographer assumes that you use Packagist (Composer) to install language packages, therefore we will expect them in vendor/ folder. There is no need to manually turn on an extra language, but if you attempt to use a non-existing language – expect an exception.

Language Countries States Cities Package
English 100% 100% 100% geographer-data
Russian 100% 100% 63% geographer-ru
Ukrainian ✓ ✓ ✓ geographer-uk
Spanish ✓ ✓ ✓ geographer-es
Italian ✓ ✓ ✓ geographer-it
French ✓ ✓ ✓ geographer-fr
German ✓ ✓ ✓ geographer-de
Chinese Mandarin ✓ ✓ ✓ geographer-zh
Danish ✓ - - geographer-da

English texts are included in the data package and are used as default metadata.

Vision

Our main principles and goals are:

  1. Be lightweight and independent – so that this package can be pulled anywhere alone
  2. Coverage – Geographer should cover all countries and languages
  3. Be extensible – developers should be able to override and extend easily

Performance

While not a number one priority at this stage, we will try maintain reasonable CPU and memory performance. Some benchmarks:

Inflating a city based on its Id

Time: 6 ms, memory: 81056 bytes

Video tutorials

I've just started a educational YouTube channel that will cover top IT trends in software development and DevOps: config.sys

Todo

  1. Add a basic spatial index
  2. Add some unit tests (in addition to existing integration tests)
  3. Add coverage information for language packages
