<p>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。</p>
<pre class="brush:php;toolbar:false;">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' => $longitude);
} else {
return false;
}
}</pre>
<p>我尝试以多种方式使用参数，但始终得到相同的结果：错误的坐标。</p><p>测试参数如下：</p><p><br /></p>
<pre class="brush:php;toolbar:false;">$address = 'VIA DUCHESSA JOLANDA'
$city = 'MONCRIVELLO'
$province = 'VC'
$postalcode = '13040'</pre>
<p>结果是纬度：45.0742756，经度：7.6613655</p><p>而正确的应该是：纬度：45.3307055，经度：7.9960788</p><p><strong></strong></p>
很抱歉，使用这个新版本后，坐标看起来是正确的。
