这是JSON输出:我只想获得formatted_address值&long_name,short_name。我提到了人们已经问过的问题，但我没有回答对。提到:
从地理编码器结果获取城市?

我的PHP函数，用于获取给定的时区和时区的反向地理编码
public function get_location()
{
$this->location = $param;
$location = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=2.993518,101.7874058&sensor=true');
return $location;
}
我试着这样解析:
$search = new search();
$data = $search->get_location();//caries the JSON data
$return['json']= json_encode($data);
$data = json_decode($return['json'], true);
但是如何定位long_name，格式化地址等等?
下面的示例演示了如何解析和访问Geocoding Service结果long_name &PHP中的short_name属性:
$json = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng=2.993518,101.7874058&sensor=true');
$data = json_decode($json, true);
foreach ($data['results'] as $item) {
if( !empty( $item['address_components'] ) ){
$longName = $item['address_components'][0]['long_name'];
$shortName = $item['address_components'][0]['short_name'];
print_r('Long Name:' . $longName);
print_r(' Short Name:' . $shortName);
}
}
PhpFiddle
首先，您可以在这里阅读有关geocoder结果类型的所有信息-> https://developers.google.com/maps/documentation/geocoding/intro
为了方便，我会将JSON转换为stdClass:
$location = json_decode($location);
然后像这样解析:
$geoResults = [];
foreach($location->results as $result){
$geoResult = [];
foreach ($result->address_components as $address) {
if ($address->types[0] == 'country') {
$geoResult['country'] = $address->long_name;
}
if ($address->types[0] == 'administrative_area_level_1') {
$geoResult['state'] = $address->long_name;
}
if ($address->types[0] == 'administrative_area_level_2') {
$geoResult['county'] = $address->long_name;
}
if ($address->types[0] == 'locality') {
$geoResult['city'] = $address->long_name;
}
if ($address->types[0] == 'postal_code') {
$geoResult['postal_code'] = $address->long_name;
}
if ($address->types[0] == 'route') {
$geoResult['route'] = $address->long_name;
}
}
$geoResults[] = $geoResult;
}
现在你有一个$geoResults数组命名属性:
Array
(
[0] => Array
(
[route] => Jalan Sungai Chua
[city] => Kajang
[state] => Selangor
[country] => Malaysia
[postal_code] => 43000
)
[1] => Array
(
[city] => Kajang
[state] => Selangor
[country] => Malaysia
[postal_code] => 43000
)
[2] => Array
(
[city] => Kajang
[state] => Selangor
[country] => Malaysia
[postal_code] => 43000
)
[3] => Array
(
[city] => Kajang
[state] => Selangor
[country] => Malaysia
)
[4] => Array
(
[state] => Selangor
[country] => Malaysia
)
[5] => Array
(
[postal_code] => 43000
[state] => Selangor
[country] => Malaysia
)
[6] => Array
(
[state] => Selangor
[country] => Malaysia
)
[7] => Array
(
[state] => Selangor
[country] => Malaysia
)
[8] => Array
(
[country] => Malaysia
)
)
你可以像这样遍历所有找到的城市:
foreach($geoResults as $result) {
echo isset($result['city']) ? $result['city'] : 'N/A';
echo '<br>';
}
