I'm using the google geocoding api. Everything is working fine. However when I search for 1 location I receive way to many information. I only need for example the administrative_area_level_1.
Url that I use:
https://maps.googleapis.com/maps/api/geocode/json?latlng=12.1224221,-68.8824233&sensor=false&key=mykey:)
I receive this:

Right now I have to do this:
json_decode($response->getBody())->results[0]->address_components[4]->long_name;
And I get the administrative_area_level_1.
Is there a better?
Reverse geocoding in Geocoding API also allows to specify a type of results that you want to get. In order to get only result of type administrative_area_level_1 add a result_type parameter in your request
https://maps.googleapis.com/maps/api/geocode/json?latlng=12.1224221%2C-68.8824233&result_type=administrative_area_level_1&key=YOUR_API_KEY
The response will contain only administrative area level 1 item, so you can retrieve a name of administrative area as
json_decode($response->getBody())->results[0]->formatted_address
or
json_decode($response->getBody())->results[0]->address_components[0]->long_name
I hope this helps!
