DEMONSTRATION

$gmaps = new \yidas\googleMaps\Client(['key'=>'Your API Key']);

// Geocoding an address
$geocodeResult = $gmaps->geocode('Taipei 101, Taipei City, Taiwan 110');

// Look up an address with reverse geocoding
$reverseGeocodeResult = $gmaps->reverseGeocode([25.0339639, 121.5644722]);

// Request directions via public transit
$directionsResult = $gmaps->directions('National Palace Museum', 'Taipei 101', [
    'mode' => "transit",
    'departure_time' => time(),
    ]);

DESCRIPTION

The PHP Client for Google Maps Services is a PHP Client library for the following Google Maps APIs:

REQUIREMENTS

This library requires the following:

PHP 5.4.0+|7.0+
guzzlehttp/guzzle 5.3.1+|6.0+
Google Maps API key or credential

API keys

Each Google Maps Web Service request requires an API key or client ID. API keys are freely available with a Google Account at https://developers.google.com/console. The type of API key you need is a Server key.

To get an API key:

Visit https://developers.google.com/console and log in with a Google Account.
Select one of your existing projects, or create a new project.
Enable the API(s) you want to use. The Client for Google Maps Services accesses the following APIs:
- Directions API
- Distance Matrix API
- Elevation API
- Geocoding API
- Geolocation API
- Places API
- Roads API
- Time Zone API
Create a new Server key.
If you'd like to restrict requests to a specific IP address, do so now.

For guided help, follow the instructions for the Directions API. You only need one API key, but remember to enable all the APIs you need. For even more information, see the guide to [API keys][apikey].

Important: This key should be kept secret on your server.

INSTALLATION

Run Composer in your project:

composer require yidas/google-maps-services

Then you could call it after Composer is loaded depended on your PHP framework:

require __DIR__ . '/vendor/autoload.php';

use yidas\googleMaps\Client;

USAGE

Before using any Google Maps Services, first you need to create a Client with configuration, then use the client to access Google Maps Services.

Client

Create a Client using API key:

$gmaps = new \yidas\googleMaps\Client(['key'=>'Your API Key']);

Google Maps APIs Premium Plan license

If you use Google Maps APIs Premium Plan license instead of an API key, you could create Client using client ID and client secret (digital signature) for authentication.

$gmaps = new \yidas\googleMaps\Client([
    'clientID' => 'Your client ID', 
    'clientSecret' => 'Your digital signature'
    ]);

Language

You could set language for Client for all services:

$gmaps = new \yidas\googleMaps\Client(['key'=>'Your API Key', 'language'=>'zh-TW']);

Changing language during execution:

$gmaps->setLanguage('zh-TW');
// ...

Directions API

// Request directions via public transit
$directionsResult = $gmaps->directions('National Palace Museum', 'Taipei 101', [
    'mode' => "transit",
    'departure_time' => time(),
    ]);

Distance Matrix API

// Get the distance matrix data between two places
$distanceMatrixResult = $gmaps->distanceMatrix('National Palace Museum', 'Taipei 101');

// With Imperial units
$distanceMatrixResult = $gmaps->distanceMatrix('National Palace Museum', 'Taipei 101', [
    'units' => 'imperial',
    ]);

Elevation API

// Get elevation by locations parameter
$elevationResult = $gmaps->elevation([25.0339639, 121.5644722]);
$elevationResult = $gmaps->elevation('25.0339639, 121.5644722');

Geocoding API

// Geocoding an address
$geocodeResult = $gmaps->geocode('Taipei 101, Taipei City, Taiwan 110');

// Look up an address with reverse geocoding
$reverseGeocodeResult = $gmaps->reverseGeocode([25.0339639, 121.5644722]);

Geolocation API

// Simple geolocate
$geolocateResult = $gmaps->geolocate([]);

Time Zone API

// requests the time zone data for giving location
$timezoneResult = $gmaps->timezone([25.0339639, 121.5644722]);
