如何从反向地理编码JSON结果中获取格式化的地址？

Question

这是JSON输出：我只想获取formatted_address值＆long_name＆short_name。我提到了人们已经问过的问题，但是我做错了。指：

从地址解析器结果中获取城市？

MY PHP函数获取给定的经纬度的反向地理编码

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;
    }

我试图这样解析：

$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？

Answer 1

以下示例演示了如何在PHP中解析和访问地址解析服务的结果long_name和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);
    }

}
