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。

846function 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; } }
