Google Maps is a service supplied by Google and first of all you must register your app project on the Google Cloud Platform Console and get a Google API key which you can add to your app or website (source: official Google Maps documentation).

1. Read the Pricing table
2. Create your project by clicking on "Get started"
3. Create project credentials
4. Enable services (Geocoding API, Elevation API, etc...)

Google Console

Google Console main page

Geocoding API

The Geocoding API is a service that provides geocoding and reverse geocoding of addresses.

Official Google Geocoding documentation

Initialize Geocoding Object

First of all replace YOUR_API_KEY with your actual API key.

use Biscolab\GoogleMaps\Api\Geocoding;
use Biscolab\GoogleMaps\Enum\GoogleMapsApiConfigFields;

$geocoding = new Geocoding([
	GoogleMapsApiConfigFields::KEY => 'YOUR_API_KEY'
]);

Get results

You have 3 different ways to retrieve data of your place!

Go to complete SDK reference

Geocoding (Latitude/Longitude Lookup) by address as string

Official Google documentation

getByAddress accept following arguments:

Name	Required	Type	Description
address	yes	string	The street address or plus code that you want to geocode
region	no	string	The region code, specified as a ccTLD ("top-level domain") two-character value. More info here

$results = $geocoding->getByAddress('Insert your address here, city, postal code etc...');

Change response language using setLanguage method

You can find the list of supported languages here: https://developers.google.com/maps/faq#languagesupport

// Set Spanish language
$results = $geocoding->setLanguage('es')->getByAddress('Insert your address here, city, postal code etc...');

Reverse Geocoding (Address Lookup) by Location/LatLng object

Official Google documentation

getByLatLng (getReverse alias is deprecated) accept a LatLng object which represents the location of the place.

$results = $geocoding->getByLatLng(new LatLng([
			LatLngFields::LAT => $lat,
			LatLngFields::LNG => $lng,
		]));

// Alias `getReverse` deprecated!!!
$results = $geocoding->getReverse(new LatLng([
			LatLngFields::LAT => $lat,
			LatLngFields::LNG => $lng,
		]));

Change response language using setLanguage method

You can find the list of supported languages here: https://developers.google.com/maps/faq#languagesupport

// Set Spanish language
$results = $geocoding->setLanguage('es')->getByLatLng(new LatLng([
			LatLngFields::LAT => $lat,
			LatLngFields::LNG => $lng,
		]));

// Use the same way for getReverse (alias) method

By Place ID as string

getByPlaceId accept as parameter the address the place ID.

$results = $geocoding->getByPlaceId('YOUR_PLACE_ID');

Use results

Results is/are a Biscolab\GoogleMaps\Http\GeocodingResultsCollection object.
First thing you should know how many results there are in your GeocodingResultsCollection using count method.

$number_of_results = $results->count();

To retrieve the first result you can use the first method:

$first_result = $results->first();

$first_result is an instance of GeocodingResult class and has the following methods:

Method name	Return Type
getAddressComponents()	Address
getFormattedAddress()	string
getGeometry()	Geometry
getPlaceId()	string
getTypes()	array

Elevation API

The Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values).

There are two types of request:

• Positional Requests
• Sampled Path Requests

At the moment this package support only Positional Requests but I'm working on Sampled Path Requests and it will be available soon.

Official Google Elevation documentation

Initialize Elevation Object

First of all replace YOUR_API_KEY with your actual API key.

use Biscolab\GoogleMaps\Api\Elevation;
use Biscolab\GoogleMaps\Enum\GoogleMapsApiConfigFields;

$elevation = new Elevation([
	GoogleMapsApiConfigFields::KEY => 'YOUR_API_KEY'
]);

Get results (Positional Requests)

First of all you have to prepare the locations variable, it can be a single Location object, an array of Location objects or a polyline string.

Single Location object

Create a Location object using latitude and longitude.

// get results by single Location object
$locations = new Location([
	LatLngFields::LAT => 39.73915360,
	LatLngFields::LNG => -104.9847034,
]);

Array of Location objects

Using multiple Location objects inside an array

// or by multiple Location objects
$locations = [
	new Location([
		LatLngFields::LAT => 39.73915360,
		LatLngFields::LNG => -104.9847034,
	]),
	// ... more locations
	new Location([
		LatLngFields::LAT => 50.123,
		LatLngFields::LNG => 99.456,
	])
];

Polyline encoded string

Encode a location using the Encoded Polyline Algorithm Format

// or by polyline
$locations = 'enc:gfo}EtohhU';

Make API call

// make API call
$results = $elevation->getByLocations($locations);

Get results (Sampled Path Requests)

First of all you have to prepare the path variable, it can be an array of Location objects or a polyline string.

Array of Location objects

Using multiple Location objects inside an array

// or by multiple Location objects
$path = [
	new Location([
		LatLngFields::LAT => 39.73915360,
		LatLngFields::LNG => -104.9847034,
	]),
	// ... more locations
	new Location([
		LatLngFields::LAT => 50.123,
		LatLngFields::LNG => 99.456,
	])
];

Polyline encoded string

Encode a location using the Encoded Polyline Algorithm Format

// or by polyline
$path = 'enc:gfo}EtohhUxD@bAxJmGF';

Make API call

// make API call
$samples = 5; // must be int > 0
$results = $elevation->getBySampledPath($path, $samples);

Use results

Results is/are a Biscolab\GoogleMaps\Http\ElevationResultsCollection object.
First thing you should know how many results there are in your ElevationResultsCollection using count method.

$number_of_results = $results->count();

To retrieve the first result you can use the first method:

$first_result = $results->first();

$first_result is an instance of ElevationResult class and has the following methods:

Method name	Return Type
getLocation()	Location
getElevation()	float
getResolution()	float

Places API

The Places API allows you to query for place information on a variety of categories, such as: establishments, prominent points of interest, geographic locations, and more. You can search for places either by proximity or a text string (credits: Official Documentation website.

There are 3 types of request:

• Find Place requests
• Nearby Search requests
• Text Search requests

Official Google Place documentation

Initialize Places Object

First of all replace YOUR_API_KEY with your actual API key.

use Biscolab\GoogleMaps\Api\Places;

$place = new Places([
	GoogleMapsApiConfigFields::KEY => 'YOUR_API_KEY'
]);
