Question

我正在尝试重新格式化地址。

所以我想使用Google地理编码API。这是一个输出

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "301",
               "short_name" : "301",
               "types" : [ "subpremise" ]
            },
            {
               "long_name" : "880",
               "short_name" : "880",
               "types" : [ "street_number" ]
            },
            {
               "long_name" : "N Street",
               "short_name" : "N St",
               "types" : [ "route" ]
            },
            {
               "long_name" : "South Addition",
               "short_name" : "South Addition",
               "types" : [ "neighborhood", "political" ]
            },
            {
               "long_name" : "Anchorage",
               "short_name" : "Anchorage",
               "types" : [ "locality", "political" ]
            },
            {

               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "99501",
               "short_name" : "99501",
               "types" : [ "postal_code" ]
            }
         ],
         "formatted_address" : "880 N Street #301, Anchorage, AK 99501, USA",
         "geometry" : {
            "location" : {
               "lat" : 61.21391800000001,
               "lng" : -149.908357

如何获取街道号码，街道地址，套件＃（如果有），城市，州，邮政编码。

令我困惑的部分是address_component具有不同的组件。我怎么知道每个人代表什么？

我以为我可以做这样的事情来得到我需要的东西

<?php
$obj = json_decode($json, true);

$c = $obj['results'][0]['address_components'];
echo '</pre>';
echo 'BUILDING NAME: ' . $c[1]['long_name'] . "<br>\n";
echo 'BUILDING NUMBER: ' . $c[2]['long_name'] . "<br>\n";
echo 'STREET NAME: ' . $c[3]['long_name'] . "<br>\n";
echo 'CITY: ' . $c[5]['long_name'] . "<br>\n";
echo 'COUNTY: ' . $c[6]['long_name'] . "<br>\n";
echo 'STATE: ' . $c[7]['short_name'] . "<br>\n";
echo 'COUNTRY: ' . $c[8]['short_name'] . "<br>\n";
echo 'POSTAL CODE: ' . $c[9]['short_name'] . "<br>\n";
?>

但这对所有地址都不起作用。使用上面的地址是我的输出。正如你所知，标签与数据不符。

BUILDING NAME: 880
BUILDING NUMBER: N Street
STREET NAME: South Addition
CITY: Anchorage
COUNTY: Alaska
STATE: US
COUNTRY: 99501

我怎样才能让每次所需的结果都正确？我的假设是，我会以某种方式检查类型值，但我不确定如何以及我需要查看的规则是什么。

这是一个快速的功能，我把它放在一起，这里是fiddle：

function getAddress($elements){ 
    $addr = []; 
    foreach($elements as $e){ 
         if(isset($e['types']) && in_array("street_number",$e['types'])) $addr['street_number'] = $e['long_name']; 
         if(isset($e['types']) && in_array("street_number",$e['types'])) $addr['route'] = $e['long_name']; 
         if(isset($e['types']) && in_array("administrative_area_level_2",$e['types'])) $addr['city'] = $e['long_name']; 
    } 
    return $addr; 
}

虽然我没有为你做所有的工作。这只是为了给你一个如何做的例子。您必须对其进行编辑以获取其余信息。

样本用法：

$obj = json_decode($json, true); 
$c = $obj['results'][0]['address_components']; 
$address_parts = getAddress($c);

输出一个简单的数组：

array(3) { ["street_number"]=> string(3) "880" ["route"]=> string(3) "880" ["city"]=> string(9) "Anchorage" }
