Maps Google API返回错误的坐标

Question

我使用这个PHP函数来获取坐标，但它们总是错误的。有时候接近，有时候离正确的位置很远。

function getCoordinates($address, $city, $postalCode, $region, $province)
{
  $url = 'https://maps.googleapis.com/maps/api/geocode/json?';
  $params = array(
      'address' => urlencode($address),
      'components' => urlencode("locality:$city|administrative_area:$province"),
      'key' => 'my_key' 
  );
  $url .= http_build_query($params);
  $response = file_get_contents($url);
  $data = json_decode($response, true);
  if ($data['status'] === 'OK') {
      $latitude = $data['results'][0]['geometry']['location']['lat'];
      $longitude = $data['results'][0]['geometry']['location']['lng'];
      return array('latitude' => $latitude, 'longitude' => $longitude);
  } else {
      return false;
  }
}

我尝试以多种方式使用参数，但始终得到相同的结果：错误的坐标。

测试参数如下：

$address = 'VIA DUCHESSA JOLANDA'
$city = 'MONCRIVELLO'
$province = 'VC'
$postalcode = '13040'

结果是纬度：45.0742756，经度：7.6613655

而正确的应该是：纬度：45.3307055，经度：7.9960788

很抱歉，使用这个新版本后，坐标看起来是正确的。

function getCoordinates1($address, $city, $postalCode, $region, $province)
{
    $url = 'https://maps.googleapis.com/maps/api/geocode/json?';
    $addressString = "$address, $postalCode, $city, $province, $region";
    $params = array(
        'address' => urlencode($addressString),
        'key' => 'my-code'
    );
    $url .= http_build_query($params);
    $response = file_get_contents($url);
    $data = json_decode($response, true);
    if ($data['status'] === 'OK') {
        $latitude = $data['results'][0]['geometry']['location']['lat'];
        $longitude = $data['results'][0]['geometry']['location']['lng'];
        return array('latitude' => $latitude, 'longitude' => $longitude);
    } else {
        return false;
    }
}
