如何解析Google地图地理编码结果

本文介绍了如何解析Google地图地理编码结果的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想使用地理编码从给定的经度和纬度检索地理位置地址，使用网站上的示例检索 maps.googleapis/maps/api/geocode/json?latlng=40.714224,- 73.961452& sensor = true 在这个例子中，我只需要城市名称纽约，国家名称即美国。但问题是这里有多个表达的词作为long_name。 我的问题如何在php中解析这个json / xml以获取城市名称和国家。

$ url = file_get_contents（'maps.googleapis/maps/api/geocode/xml?latlng=40.714 224，-73.961452& sensor = true'）; $ xml = simplexml_load_string（$ url）; $ tracks = $ xml->结果; $ temp; $城市; $国家; foreach（$ track为$ key） { foreach（$ key-> address_component as $ val） { $ temp = $ val-> LONG_NAME; if（$ val-> type ==locality） { $ city = $ temp; } else if（$ val-> type ==country） { $ country = $ temp; } } } echo $ country。< br />; echo $ city; <？xml version =1.0encoding =UTF-8？> < GeocodeResponse> < status>确定< / status> <结果> < type> street_address< / type> <

解决方案

您可以在google响应中检查3个变量json）找到当前的城市名称。因此，有3种不同的名称解释：

国家 | AdministrativeArea | | _AdministrativeAreaName（cityname） | | _Locality_LocalityName（cityname） | | _SubAdministrativeArea | | _Locality_LocalityName（cityname） if（$ this-> json->地标[0] - > AddressDetails-> Country-> ; AdministrativeArea-> Locality-> LocalityName！= NULL）{ $ code ['cityname'] = $ this-> json->地标[0] - > AddressDetails-> ;国家 - > AdministrativeArea-> Locality->处所名称; } elseif（$ this-> json-> Placemark [0] - > AddressDetails-> Country-> AdministrativeArea-> SubAdministrativeArea-> Locality-> LocalityName！= NULL）{ $ code ['cityname'] = $ this-> json->地标[0] - > AddressDetails-> Country-> AdministrativeArea-> SubAdministrativeArea-> ; Locality->处所名称; $ b

如果你有更多的地标，你需要遍历所有数组。

I want to retrieve Geo address from given latitude and longitude using geocoding, using the given example on the site maps.googleapis/maps/api/geocode/json?latlng=40.714224,-73.961452&sensor=true I just need city name New York in this example and country name i.e United States. But the problem is there are more than one appearances of these words as long_name. My question how can I parse this json/xml in php to get just city name and country.

$url= file_get_contents('maps.googleapis/maps/api/geocode/xml?latlng=40.714‌​224,-73.961452&sensor=true'); $xml = simplexml_load_string($url); $tracks = $xml->result; $temp; $city; $country; foreach($tracks as $key) { foreach($key->address_component as $val) { $temp= $val->long_name; if($val->type=="locality") { $city=$temp; }else if($val->type=="country") { $country=$temp; } } } echo $country."<br />"; echo $city; <?xml version="1.0" encoding="UTF-8"?> <GeocodeResponse> <status>OK</status> <result> <type>street_address</type> <formatted_address>277 Bedford Avenue, Brooklyn, New

解决方案

You can check for 3 variables in the google response (json) to find the current cityname. Hence there is 3 different interpretation of the name:

Country | AdministrativeArea | |_AdministrativeAreaName (cityname) | |_Locality_LocalityName (cityname) | |_SubAdministrativeArea | |_Locality_LocalityName (cityname) if ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->Locality->LocalityName; } elseif ($this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName != NULL) { $code['cityname'] = $this->json->Placemark[0]->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->Locality->LocalityName; }

If you have more then a Placemark you need to loop through all the array.
