Question

我想用反轉地理編碼獲取座標的城市和國家。

這裏有兩個例子：

Hamburg, Germany

Bangkok, Thailand

我總是需要第一address_components，然後將兩種類型的價值觀[ "locality" ]和[ "country", "political" ]但我不知道該如何對付它們。

我有什麼至今：

$url = 'https://maps.googleapis.com/maps/api/geocode/json?latlng=' . get_wpgeo_latitude($post_id) . ',' . get_wpgeo_longitude($post_id) . '&language=de'; 
$data = @file_get_contents($url); 
$jsondata = json_decode($data, true); 

print_r($jsondata['results'][0]['address_components'][0]); 

Answer 1

如果你需要得到城市和國家嘗試這種

foreach($jsondata['results'] as $r){ 
    //print_r($r); 
    foreach($r['address_components'] as $n){ 
     //print_r($n); 
     if($n['types'][0] == "locality" && $n['types'][1] == "political"){ 
      $city = $n['long_name']; 
     } 

     if($n['types'][0] == "country" && $n['types'][1] == "political"){ 
      $country = $n['long_name']; 
     } 

    } 

} 

echo $city. ", ". $country. "</br>";
