请求Google Maps Geolocation API

Question

我想通过使用PHP 5来请求Web服务 - Google Geolocation API.我有使用PHP进行XML解析的经验,但是这个使用JSON格式来发出请求.我不知道如何提出要求!我认为接收请求类似于XML解析!

试试这个(结果是json格式):

public function getGeoPosition($address){
    $url = "http://maps.google.com/maps/api/geocode/json?sensor=false" . 
        "&address=" . urlencode($address);

    $json = file_get_contents($url);

    $data = json_decode($json, TRUE);

     if($data['status']=="OK"){
      return $data['results'];
    }

}

print_r(getGeoPosition('chicago,il'));
