我想获得国家，pincode，州和城市名称从经度和纬度在谷歌地图API -与PHP。但有时它工作正确，但有时它得到错误的信息，很多时候它返回空值，因为结果是动态的，而不是固定的。
有谁能告诉我如何使其动态化并检查其国家，城市，pincode和状态可以在result ....
中的任何数组索引中找到下面是我的代码…
$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;
我需要检查地址组件中的类型，如下面的result forloop，如果可用，然后显示结果。
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

正确提取地址组件值的方法如下:
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);
}
}
我有一些已知可以工作的类似代码。基本上，如果可能有多个结果，它可以返回一个结果数组;如果只找到一个结果，它可以只返回一个对象。我的用例略有不同，但希望它能有所帮助。试试这个:
$ch = curl_init();
$geoCodeUrl = 'https://maps.googleapis.com/maps/api/geocode/json?address=' . $zip . ',+United+States&key=' . $googleApiKey;
curl_setopt($ch,CURLOPT_URL, $geoCodeUrl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
$result = curl_exec($ch);
curl_close($ch);
$GeoCode = json_decode($result);
$GeoLocator = new 'stdClass();
if( isset($GeoCode->results[0]) ){
$GeoLocator->lat = $GeoCode->results[0]->geometry->location->lat;
$GeoLocator->lon = $GeoCode->results[0]->geometry->location->lng;
foreach($GeoCode->results[0]->address_components as $comp){
if( in_array('locality',$comp->types) ){
$GeoLocator->city = trim($comp->short_name);
}
else if( in_array('administrative_area_level_1',$comp->types) ){
$GeoLocator->state = strtoupper(trim(preg_replace('/'d/', '', $comp->short_name)));
}
}
}
else if( isset($GeoCode->results) && isset($GeoCode->results->geometry) ){
$GeoLocator->lat = $GeoCode->results->geometry->location->lat;
$GeoLocator->lon = $GeoCode->results->geometry->location->lng;
foreach($GeoCode->results->address_components as $comp){
if( in_array('locality',$comp->types) ){
$GeoLocator->city = trim($comp->short_name);
}
else if( in_array('administrative_area_level_1',$comp->types) ){
$GeoLocator->state = strtoupper(trim(preg_replace('/'d/', '', $comp->short_name)));
}
}
}
