$response = $geocoder->reverse('38.9002898,-76.9990361');
$response = $geocoder->reverse([38.9002898, -76.9990361]);

Batch geocoding

To batch geocode, simply pass an array of addresses or coordinates instead of a single string

$response = $geocoder->geocode([
    '1109 N Highland St, Arlington VA',
    '525 University Ave, Toronto, ON, Canada',
    '4410 S Highway 17 92, Casselberry FL',
    '15000 NE 24th Street, Redmond WA',
    '17015 Walnut Grove Drive, Morgan Hill CA'
]);

$response = $geocoder->reverse([
    '35.9746000,-77.9658000',
    '32.8793700,-96.6303900',
    '33.8337100,-117.8362320',
    '35.4171240,-80.6784760'
]);

// Optionally supply a custom key that will be returned along with results
$response = $geocoder->geocode([
    'MyId1' => '1109 N Highland St, Arlington VA',
    'MyId2' => '525 University Ave, Toronto, ON, Canada',
    'MyId3' => '4410 S Highway 17 92, Casselberry FL',
    'MyId4' => '15000 NE 24th Street, Redmond WA',
    'MyId5' => '17015 Walnut Grove Drive, Morgan Hill CA'
]);

Field appends

Geocodio allows you to append additional data points such as congressional districts, census codes, timezone, ACS survey results and much much more.

To request additional fields, simply supply them as an array as the second parameter

$response = $geocoder->geocode(
    [
        '1109 N Highland St, Arlington VA',
        '525 University Ave, Toronto, ON, Canada'
    ],
    [
        'cd',
        'timezone'
    ]
);

$response = $geocoder->reverse('38.9002898,-76.9990361', ['census2010']);

Address components

For forward geocoding requests it is possible to supply individual address components instead of a full address string. This works for both single and batch geocoding requests.

$response = $geocoder->geocode([
    'street' => '1109 N Highland St',
    'city' => 'Arlington',
    'state' => 'VA',
    'postal_code' => '22201'
]);

$response = $geocoder->geocode([
    [
        'street' => '1109 N Highland St',
        'city' => 'Arlington',
        'state' => 'VA'
    ],
    [
        'street' => '525 University Ave',
        'city' => 'Toronto',
        'state' => 'ON',
        'country' => 'Canada',
    ],
);

Limit results

Optionally limit the number of maximum geocoding results by using the third parameter on geocode(...) or reverse(...)

$response = $geocoder->geocode('1109 N Highland St, Arlington, VA', [], 1); // Only get the first result
$response = $geocoder->reverse('38.9002898,-76.9990361', ['timezone'], 5); // Return up to 5 geocoding results

Usage with Laravel

This library works well without Laravel, but if you happen to be using Laravel you can enjoy a few Laravel-specific features.

The package will be auto-discovered by newer Laravel versions, so the only thing left to do is to publish the config file

php artisan vendor:publish --provider="Geocodio\GeocodioServiceProvider"

You can now go ahead and edit your config file at config/geocodio.php.

You will now be able to use the Geocodio facade, or dependency inject the fully-configured Geocodio class.

// Using facade
use Geocodio;

$response = Geocodio::geocode('1109 N Highland St, Arlington, VA');

// Using dependency injection
use Geocodio\Geocodio;

class SomeController {
  public function __construct(Geocodio $geocoder) {
      $response = $geocoder->geocode('1109 N Highland St, Arlington, VA');
  }
}
