Access Google Maps Roads API in PHP
- Ensure you have the appropriate API key with access to the Roads API. You will need this key to authenticate your requests.
- PHP does not have a direct library for Google Maps Roads API, so you will typically use cURL or a library like Guzzle to make HTTP requests.
- When using cURL, set up a function to make HTTP GET requests to the Roads API.
function getRoadsApiData($path, $apiKey) {
$endpoint = "https://roads.googleapis.com/v1/snapToRoads?path=$path&key=$apiKey";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
return json_decode($response, true);
}
$path = "60.170880,24.942795|60.170879,24.942796"; // Sample path coordinates
$apiKey = "YOUR_API_KEY_HERE"; // Replace with your API key
$result = getRoadsApiData($path, $apiKey);
print_r($result);
- Alternatively, if using Guzzle, set up a GET request like the one shown below:
require 'vendor/autoload.php';
use GuzzleHttp\Client;
function getRoadsDataUsingGuzzle($path, $apiKey) {
$client = new Client();
$endpoint = "https://roads.googleapis.com/v1/snapToRoads?path=$path&key=$apiKey";
$response = $client->request('GET', $endpoint);
return json_decode($response->getBody(), true);
}
$path = "60.170880,24.942795|60.170879,24.942796";
$apiKey = "YOUR_API_KEY_HERE";
$result = getRoadsDataUsingGuzzle($path, $apiKey);
print_r($result);
- Handle the response to extract desired information about snapped points, place IDs, or other data based on your application's needs.
- In case of an error, check the response status and error messages to troubleshoot issues related to quota limits, invalid API keys, or incorrect request formats.
if (isset($result['error'])) {
echo "Error: " . $result['error']['message'];
} else {
foreach ($result['snappedPoints'] as $point) {
echo "Location: (" . $point['location']['latitude'] . ", " . $point['location']['longitude'] . ") Place ID: " . $point['placeId'] . "\n";
}
}
- Ensure your endpoints are secured and that sensitive information such as API keys is protected and not hardcoded directly into your code base.
