php - Getting street,city and country by reverse geocoding using google

Question

I'm trying to getting the $street, $city and $country string from google json. It works for my home address : http://maps.googleapis.com/maps/api/geocode/json?latlng=52.108662,6.307370&sensor=true

$url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=".$lat.",".$lng."&sensor=true";
    $data = @file_get_contents($url);
    $jsondata = json_decode($data,true);
    if(is_array($jsondata) && $jsondata['status'] == "OK")
    {
          $city = $jsondata['results']['0']['address_components']['2']['long_name'];
          $country = $jsondata['results']['0']['address_components']['5']['long_name'];
          $street = $jsondata['results']['0']['address_components']['1']['long_name'];
    }

But for a different address with more data in the arrays like this example: http://maps.googleapis.com/maps/api/geocode/json?latlng=52.154184,6.199592&sensor=true it doesn't work, because there is more data in the json array and it makes the province the country.

How can I select the type that I need (long_name)?

• for street : long_name where "types" : [ "route" ]
• for city : long_name where "types" : [ "locality", "political" ]
• for country : long_name where "types" : [ "country", "political" ]

Example output from the geocode JSON:

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "89",
               "short_name" : "89",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "Wieck De",
               "short_name" : "Wieck De",
               "types" : [ "establishment" ]
            },
            {
               "long_name" : "Industrieweg",
               "short_name" : "Industrieweg",
               "types" : [ "route" ]
            },
            {
               "long_name" : "Zutphen",
               "short_name" : "Zutphen",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Zutphen",
               "short_name" : "Zutphen",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "Gelderland",
               "short_name" : "GE",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "Nederland",
               "short_name" : "NL",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "7202 CA",
               "short_name" : "7202 CA",
               "types" : [ "postal_code" ]
            }

I think I fixed it myself, hereby my code:

// street
foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("route", $address["types"])) {
            $street = $address["long_name"];
        }
    }
}
// city
foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("locality", $address["types"])) {
            $city = $address["long_name"];
        }
    }
}
// country
foreach ($jsondata["results"] as $result) {
    foreach ($result["address_components"] as $address) {
        if (in_array("country", $address["types"])) {
            $country = $address["long_name"];
        }
    }
}

You could convert the data to the associative array and work with it like

 $data = array();
 foreach($jsondata['results']['0']['address_components'] as $element){
     $data[ implode(' ',$element['types']) ] = $element['long_name'];
 }
 print_r($data);

 echo 'route: ' . $data['route'] . "
";
 echo 'country: ' . $data['country political'];
