Maps Google API returns wrong coordinates

Question

I use this PHP function to get the coordinates but they are always wrong. Sometimes close, sometimes far from the right spot.

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;
  }
}

I tried using the parameters in many ways but always got the same result: wrong coordinates.

The test parameters are as follows:

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

The result is latitude: 45.0742756, longitude: 7.6613655

The correct one should be: latitude: 45.3307055, longitude: 7.9960788

Sorry, the coordinates look correct after using this new version.

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;
    }
}
