Get State and County from Address

Question

I want to have the State and county from an Address using geocode with Google API. This is my code:

$geocode=file_get_contents('http://maps.google.com/maps/api/geocode/json?address='.$street.''.$plz.''.$city.'&sensor=false');
        $output= json_decode($geocode);
        $lat = $output->results[0]->geometry->location->lat;
        $long = $output->results[0]->geometry->location->lng;
        $formatted_adress = $output->results[0]->formatted_address;
        $state = $output->results[0]->address_components->administrative_area_level_2;
        $county = $output->results[0]->address_components->administrative_area_level_1;

latitude, longitude and formatted_adress works find and I can save the results in my database, but the state and county doesn't work.

This is the output:

    {
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Hauptgasse",

Answer 1

According to your json data that you show you need to get state and county like below:-

$state = $output->results[0]->address_components[2]->long_name;// i assume `Solothurn` is state name
$county = $output->results[0]->address_components[4]->long_name; // i assume `Schweiz` is county name

if county name also Solothurn then just change county code like below:-

$county = $output->results[0]->address_components[3]->long_name;
