Installation

You can install the package via composer:

composer require geocodio/geocodio-library-php

Using Laravel? Great! There's an optional Laravel service provider, for easy integration into your app.

Usage

Don't have an API key yet? Sign up at https://dash.geocod.io to get an API key. The first 2,500 lookups per day are free.

Single geocoding

Using the Laravel integration? Check out Laravel-specific usage examples below.

$geocoder = new Geocodio\Geocodio();
$geocoder->setApiKey('YOUR_API_KEY');
// $geocoder->setHostname('api-hipaa.geocod.io'); // optionally overwrite the API hostname

$response = $geocoder->geocode('1109 N Highland St, Arlington, VA');
dump($response);

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

Note: You can read more about accuracy scores, accuracy types, input formats and more at https://www.geocod.io/docs/

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

Uploading Lists

The lists API lets you upload and process spreadsheet with addresses or coordinates. Similar to the spreadsheet feature in the dashboard, the spreadsheet will be processed as a job on Geocodio's infrastructure and can be downloaded at a later time. While a spreadsheet is being processed it is possible to query the status and progress.

Important

Data for spreadsheets processed through the lists API are automatically deleted 72 hours after they have finished processing. In addition to a 1GB file size limit, we recommend a maximum of 10M lookups per list batch. Larger batches should be split up into multiple list jobs.

See the API docs for geocoding lists for additional details.

Upload list from a file

Creates a new spreadsheet list job and starts processing the list in the background. The response returns a list id that can be used to retrieve the job progress as well as download the processed list when it has completed.

$response = $geocoder->uploadList(
    file: 'path/to/file.csv',
    direction: GeocodeDirection::Forward,
    format: '{{B}} {{C}} {{D}} {{E}}',
    callbackWebhook: 'https://example.com/callbacks/list-upload',
);

/*
array:2 [
  "id" => 11953719
  "file" => array:3 [
    "headers" => array:5 [
      0 => "Name"
      1 => "Address"
      2 => "City"
      3 => "State"
      4 => "Zip"
    ]
    "estimated_rows_count" => 4
    "filename" => "simple.csv"
  ]
]
*/

Upload list of inline data

$csvData = <<<'CSV'
name,street,city,state,zip
"Peregrine Espresso","660 Pennsylvania Ave SE",Washington,DC,20003
"Lot 38 Espresso Bar","1001 2nd St SE",Washington,DC,20003
CSV;

$geocodio->uploadInlineList(
    $csvData,
    'coffee-shops.csv',
    GeocodeDirection::Forward,
    '{{B}} {{C}} {{D}} {{E}}'
);

List status

View the metadata and status for a single uploaded list.

$geocoder->listStatus(11950669);

/*

  "id" => 11953719
  "fields" => []

]
*/

Download a list

Download a fully geocoded list, the returned format will always be a UTF-8 encoded, comma-separated csv file.

$geocoder->downloadList(11950669, 'path/to/file.csv');

Fetch all uploaded lists

Show all lists that have been created. The endpoint is paginated, showing 15 lists at a time, ordered by recency.

$geocoder->lists();

/*

  "current_page" => 1
  "data" => array:1 [

  "per_page" => 15
  "prev_page_url" => null

]
*/

Delete uploaded list

Delete a previously uploaded list and its underlying spreadsheet data permanently. This can also be used to cancel and delete a spreadsheet that is currently processing.

Geocodio Unlimited customers can cancel a spreadsheet at any time. Pay as You Go customers can only cancel a spreadsheet if it was just recently started.

The spreadsheet data will always be deleted automatically after 72 hours if it is not deleted manually first.

$geocoder->deleteList(11950669);

Distance calculations

Calculate distances from a single origin to multiple destinations, or compute full distance matrices.

Coordinate format with custom IDs

You can add custom identifiers to coordinates using the lat,lng,id format. The ID will be returned in the response, making it easy to match results back to your data:

// String format with ID
'37.7749,-122.4194,warehouse_1'

// Array format with ID
[37.7749, -122.4194, 'warehouse_1']

// The ID is returned in the response:
// [
//     'query' => '37.7749,-122.4194,warehouse_1',
//     'location' => [37.7749, -122.4194],
//     'id' => 'warehouse_1',
//     'distance_miles' => 3.2,
//     'distance_km' => 5.1
// ]

Distance mode and units

The SDK provides enums for type-safe distance configuration:

use Geocodio\Enums\DistanceMode;
use Geocodio\Enums\DistanceUnits;
use Geocodio\Enums\DistanceOrderBy;
use Geocodio\Enums\DistanceSortOrder;

// Available modes
DistanceMode::Straightline  // Default - great-circle (as the crow flies)
DistanceMode::Driving       // Road network routing with duration

// Available units
DistanceUnits::Miles  // Default
DistanceUnits::Km

// Sorting options
DistanceOrderBy::Distance  // Default
DistanceOrderBy::Duration

DistanceSortOrder::Asc   // Default
DistanceSortOrder::Desc

Note: The default mode is straightline (great-circle distance). Use DistanceMode::Driving if you need road network routing with duration estimates.

Add distance to geocoding requests

You can add distance calculations to existing geocode or reverse geocode requests. Each geocoded result will include a destinations array with distances to each destination.

use Geocodio\Enums\DistanceMode;
use Geocodio\Enums\DistanceUnits;
use Geocodio\Enums\DistanceOrderBy;
use Geocodio\Enums\DistanceSortOrder;

// Geocode an address and calculate distances to store locations

    ],

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');
  }
}
