Important: You are browsing the documentation of Geocoder 4.x.

Documentation for version 3.x is available here: Geocoder 3.x documentation.

Documentation for version 2.x is available here: Geocoder 2.x documentation.


Geocoder is a PHP library which helps you build geo-aware applications by providing a powerful abstraction layer for geocoding manipulations.

Installation

To install a Geocoder there are two things you need to know:

  1. What Geocoder provider you want to use
  2. What HTTP client/adapter you want to use.

Geocoder providers

Since 4.0 we do not include providers by default. You need to select a geocoder provider. You will see a list of providers at Packagist

HTTP Clients

In order to talk to geocoding APIs, you need HTTP adapters. While it was part of the library in Geocoder before, Geocoder 4.x and upper now relies on PSR-18 which defines how HTTP message should be sent and received. You can use any library to send HTTP messages that implements psr/http-client-implementation.

Read more about PSR-18 in this blog.

Summary (Just give me the command)

To install Google Maps geocoder with Guzzle 7 you may run the following command:

composer require geocoder-php/google-maps-provider guzzlehttp/guzzle

Or using the curl client (you'll need to provide a PSR7 implementation such as nyholm/psr7 if not using Guzzle)

composer require geocoder-php/google-maps-provider php-http/curl-client nyholm/psr7

Cookbook

We have a small cookbook where you can find examples on common use cases:

Usage

In the code snippet below we use GoogleMaps and Guzzle 7.

use Geocoder\Query\GeocodeQuery;
use Geocoder\Query\ReverseQuery;

$httpClient = new \GuzzleHttp\Client();
$provider = new \Geocoder\Provider\GoogleMaps\GoogleMaps($httpClient, null, 'your-api-key');
$geocoder = new \Geocoder\StatefulGeocoder($provider, 'en');

$result = $geocoder->geocodeQuery(GeocodeQuery::create('Buckingham Palace, London'));
$result = $geocoder->reverseQuery(ReverseQuery::fromCoordinates(...));

The Provider interface has three methods:

The Geocoder interface extends the Provider interface and exposes two additional methods. They will make migration from 3.x smoother.

Providers

Providers perform the geocoding black magic for you (talking to the APIs, fetching results, dealing with errors, etc.) and are highly configurable.

Special Geocoders and Providers

The Chain Provider

The Chain provider is a special provider that takes a list of providers and iterates over this list to get information. Note that it stops its iteration when a provider returns a result. The result is returned by GoogleMaps because FreeGeoIp and HostIp cannot geocode street addresses. BingMaps is ignored.

use Geocoder\Query\GeocodeQuery;

$geocoder = new \Geocoder\ProviderAggregator();
$client  = new \GuzzleHttp\Client();

$chain = new \Geocoder\Provider\Chain\Chain([
    new \Geocoder\Provider\FreeGeoIp\FreeGeoIp($client),
    new \Geocoder\Provider\HostIp\HostIp($client),
    new \Geocoder\Provider\GoogleMaps\GoogleMaps($client, 'France'),
    new \Geocoder\Provider\BingMaps\BingMaps($client, '<API_KEY>'),
    // ...
]);

$geocoder->registerProvider($chain);

$result = $geocoder->geocodeQuery(GeocodeQuery::create('10 rue Gambetta, Paris, France'));
var_export($result);

Everything is ok, enjoy!

The ProviderAggregator

The ProviderAggregator is used to register several providers so that you can decide which provider to use later on.

use Geocoder\Query\GeocodeQuery;
use Geocoder\Query\ReverseQuery;

$client  = new \GuzzleHttp\Client();
$geocoder = new \Geocoder\ProviderAggregator();

$geocoder->registerProviders([
    new \Geocoder\Provider\GoogleMaps\GoogleMaps($client),
    new \Geocoder\Provider\GoogleMaps\GoogleMapsBusiness($client, '<CLIENT_ID>'),
    new \Geocoder\Provider\Yandex\Yandex($client),
    new \Geocoder\Provider\MaxMind\MaxMind($client, '<MAXMIND_API_KEY>'),
    new \Geocoder\Provider\ArcGISOnline\ArcGISOnline($client),
]);

$geocoder->registerProvider(new \Geocoder\Provider\Nominatim\Nominatim($adapter, 'https://your.nominatim.server'));

$geocoder
    ->using('google_maps')
    ->geocodeQuery(GeocodeQuery::create( ... ));

$geocoder
    ->limit(10)
    ->reverseQuery(ReverseQuery::fromCoordinates($lat, $lng));

The ProviderAggregator's API is fluent, meaning you can write:

use Geocoder\Query\GeocodeQuery;

$locations = $geocoder
    ->registerProvider(new \My\Provider\Custom($adapter))
    ->using('custom')
    ->limit(10)
    ->geocodeQuery(GeocodeQuery::create( ... ));

The using() method allows you to choose the provider to use by its name. When you deal with multiple providers, you may want to choose one of them. The default behavior is to use the first one but it can be annoying.

The limit() method allows you to configure the maximum number of results being returned. Depending on the provider you may not get as many results as expected, it is a maximum limit, not the expected number of results.

TimedGeocoder

The TimedGeocoder class profiles each geocode and reverse call. So you can easily figure out how many time/memory was spent for each geocoder/reverse call.

use Geocoder\Query\GeocodeQuery;

// configure your provider
$provider = // ...

$stopwatch = new \Symfony\Component\Stopwatch\Stopwatch();
$geocoder = new \Geocoder\TimedGeocoder($provider, $stopwatch);

$geocoder->geocodeQuery(GeocodeQuery::create('Paris, France'));

// Now you can debug your application

We use the symfony/stopwatch component under the hood. Which means, if you use the Symfony framework the geocoder calls will appear in your timeline section in the Web Profiler.

StatefulGeocoder

The StatefulGeocoder class is great when you want your Geocoder to hold state. Say you want to configure locale, limit or bounds in runtime. The StatefulGeocoder will append these values on each query.

use Geocoder\Query\GeocodeQuery;

// configure your provider
$provider = // ...
$geocoder = new \Geocoder\StatefulGeocoder($provider);

$geocoder->setLocale('en');
$results = $geocoder->geocodeQuery(GeocodeQuery::create('London'));
echo $results->first()->getLocality(); // London

$geocoder->setLocale('es');
$results = $geocoder->geocodeQuery(GeocodeQuery::create('London'));
echo $results->first()->getLocality(); // Londres

Dumpers

Geocoder provides dumpers that aim to transform a Location object in standard formats.

GPS eXchange Format (GPX)

The GPS eXchange format is designed to share geolocated data like point of interests, tracks, ways, but also coordinates. Geocoder provides a dumper to convert a Location object in an GPX compliant format.

Assuming we got a $location object as seen previously:

$dumper = new \Geocoder\Dumper\Gpx();
$strGpx = $dumper->dump($location);

echo $strGpx;

It will display:

<gpx
    version="1.0"
    creator="Geocoder" version="1.0.1-dev"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://www.topografix.com/GPX/1/0"
    xsi:schemaLocation="http://www.topografix.com/GPX/1/0 http://www.topografix.com/GPX/1/0/gpx.xsd">
    <bounds minlat="2.388911" minlon="48.863151" maxlat="2.388911" maxlon="48.863151"/>
    <wpt lat="48.8631507" lon="2.3889114">
        <name><![CDATA[Paris]]></name>
        <type><![CDATA[Address]]></type>
    </wpt>
</gpx>

GeoJSON

GeoJSON is a format for encoding a variety of geographic data structures.

GeoArray

Simple PHP array format for using with your own encoders.

Keyhole Markup Language (KML)

Keyhole Markup Language is an XML notation for expressing geographic annotation and visualization within Internet-based, two-dimensional maps and three-dimensional Earth browsers.

Well-Known Binary (WKB)

The Well-Known Binary (WKB) representation for geometric values is defined by the OpenGIS specification.

Well-Known Text (WKT)

Well-known text (WKT) is a text markup language for representing vector geometry objects on a map, spatial reference systems of spatial objects and transformations between spatial reference systems.

Formatters

A common use case is to print geocoded data. Thanks to the StringFormatter class, it's simple to format a Location object as a string:

// $location is an instance of Location
$formatter = new \Geocoder\Formatter\StringFormatter();

$formatter->format($location, '%S %n, %z %L');
// 'Badenerstrasse 120, 8001 Zuerich'

$formatter->format($location, '<p>%S %n, %z %L</p>');
// '<p>Badenerstrasse 120, 8001 Zuerich</p>'

Unit Tests

In order to run the test suite, install the development dependencies:

composer install --dev

Then, run the following command:

composer test

You'll obtain some skipped unit tests due to the need of API keys.

Rename the phpunit.xml.dist file to phpunit.xml, then uncomment the following lines and add your own API keys:

<php>
    <!-- <server name="IPINFODB_API_KEY" value="YOUR_API_KEY" /> -->
    <!-- <server name="BINGMAPS_API_KEY" value="YOUR_API_KEY" /> -->
    <!-- <server name="GEOIPS_API_KEY" value="YOUR_API_KEY" /> -->
    <!-- <server name="MAXMIND_API_KEY" value="YOUR_API_KEY" /> -->
    <!-- <server name="GEONAMES_USERNAME" value="YOUR_USERNAME" /> -->
    <!-- <server name="TOMTOM_MAP_KEY" value="YOUR_MAP_KEY" /> -->
    <!-- <server name="GOOGLE_GEOCODING_KEY" value="YOUR_GEOCODING_KEY" /> -->
    <!-- <server name="OPENCAGE_API_KEY" value="YOUR_API_KEY" /> -->
