我想通过Google地图API从经度和纬度获取国家/地区，密码，州和城市名称。但有时它的工作正确，但有时它会得到错误的信息，很多时候会返回空值，因为结果是动态的而不是固定的。
所以任何人都建议我如何使这个动态和内部检查是国家城市pincode和状态可用于任何数组索引从结果....
下面是我的代码......
$fromlat = $this->request->data['Order']['from_lat'];
$fromlong = $this->request->data['Order']['from_long'];
$geocode = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng='.$fromlat.','.$fromlong.'&sensor=false');
$json = json_decode($geocode);
//print_r($geocode);
$country = $json->{'results'}[1]->{'address_components'}[3]->{'long_name'};
$state = $json->{'results'}[1]->{'address_components'}[2]->{'long_name'};
$city = $json->{'results'}[1]->{'address_components'}[1]->{'long_name'};
$locality = $json->{'results'}[1]->{'address_components'}[0]->{'long_name'};
$pincode = $json->{'results'}[1]->{'address_components'}[4]->{'long_name'};
echo $locality."</br>".$country."</br>".$state."</br>".$city."</br>".$pincode;
我需要在结果forloop中检查地址组件中的类型，如果可用，则显示结果。
types = country = country name;
types = administrative_area_level_1 = state name ;
types = administrative_area_level_2 = city name ;
types = postal_code = pincode ;
下面是我的结果数组......

提取地址分量值的正确方法如下：
if (results[0]) {
$("input[name=lat]").val(results[0].geometry.location.lat());
$("input[name=lng]").val(results[0].geometry.location.lng());
var addressArr = [];
$.each(results[0].address_components, function (key, val) {
if (!$.inArray("country", results[0].address_components[key].types)) {
addressArr['country'] = results[0].address_components[key].long_name;
}
if (!$.inArray("administrative_area_level_1", results[0].address_components[key].types)) {
addressArr['state'] = results[0].address_components[key].long_name;
}
if (!$.inArray("administrative_area_level_2", results[0].address_components[key].types)) {
addressArr['city'] = results[0].address_components[key].long_name;
}
});
console.log(addressArr);
}
}

我有一些类似的代码可以使用。基本上，如果可能有多个结果，它可以返回结果数组，如果只找到一个结果，则只返回一个对象。我的用例略有不同，但希望它有所帮助。试试这个：
1 | (100) - (50 + 0) = 50 |
1 | (100) - (30 + 50) = 20 |
2 | (200) - (20 + 0) = 180 |
2 | (200) - (150 + 20) = 30 |
