What are some alternative solutions for geocoding addresses in PHP if the Google Maps API quota is exceeded?

If the Google Maps API quota is exceeded, one alternative solution for geocoding addresses in PHP is to use other geocoding services such as OpenStreetMap Nominatim or Bing Maps API. These services offer free geocoding options with their own API keys and usage limits. By switching to a different geocoding service, you can continue to geocode addresses without relying solely on the Google Maps API.

// Example using OpenStreetMap Nominatim API for geocoding addresses
$address = urlencode('1600 Amphitheatre Parkway, Mountain View, CA');
$url = 'https://nominatim.openstreetmap.org/search?q=' . $address . '&format=json';
$response = file_get_contents($url);
$data = json_decode($response, true);

$latitude = $data[0]['lat'];
$longitude = $data[0]['lon'];

echo "Latitude: " . $latitude . "<br>";
echo "Longitude: " . $longitude;
