PHP library that knows how countries and cities are called in any language

Geographer

Geographer is a PHP library that knows how any country, state or city is called in any language.

Includes integrations with: Laravel 5, Lumen 5

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": "~0.1"
    }
}

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->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

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

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

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

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->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

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 (only US, CH, BE and ME) 
$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) 

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

Usage in Laravel 5

Good news is that Laravel will take care of singleton instance for you, so no matter how many times you call it – it's the same object.

// Add in your config/app.php

'providers' => [
    '...',
    MenaraSolutions\Geographer\Integrations\LaravelServiceProvider::class,
];

'aliases' => [
    '...',
    'Geographer' => MenaraSolutions\Geographer\Integrations\LaravelFacade::class,
];

// Start playing with it, all the same calls
Geographer::getCountries()->useShortNames()->toArray();

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

Todo

1. Add basic spatial index
2. Add some unit tests (in addition to existing integration tests)
3. Add ISO 3166-2 for the rest of the states
4. Move Laravel integration out to a separate package
5. Move languages (translations) to separate packages

Projects using Geographer

• Boogie Call – Music event finder
• Rapport – Real-time random photo and video streams
