Question

我收到了

的输出

http://maps.google.com/maps/api/geocode/json?address={$address}

采用JSON格式。然后像这样拉出纬度和经度

$lati = $resp['results'][0]['geometry']['location']['lat'];
$longi = $resp['results'][0]['geometry']['location']['lng'];

所有这些都很有效。但我还需要这里包含的县名

...
"results" : [
      {
         "address_components" : [
            {
               "long_name" : "Platte City",
               "short_name" : "Platte City",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Carroll Township",
               "short_name" : "Carroll Township",
               "types" : [ "administrative_area_level_3", "political" ]
            },
            {
               "long_name" : "Platte County",
               "short_name" : "Platte County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "Missouri",
               "short_name" : "MO",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            },
            {
               "long_name" : "64079",
               "short_name" : "64079",
               "types" : [ "postal_code" ]
            }
         ],
...

我试过

for ($i = 0; $i < 10; $i++) {
$type2 = $resp['results'][0]['address_components'][$i]['types'];
if (stripos(strtolower($type2), 'administrative_area_level_2') !== false){

    $county = $resp['results'][0]['address_components'][$i]['long_name'];

                } else {$county = "$i Unknown County";}
        }

正如你所看到的，县位于＆＃34; administrative_area_level_2＆＃34;但经过几个小时的努力，我得到的就是“未知县”＃39; Google API声明它不会始终位于XML / JSON中的相同位置，而且似乎是正确的。有时它位于第3位，有时在5位有时在其他地方。有人能给我一个如何获得县名的例子。

Answer 1

    // Routine to find the County name
      foreach ($resp['results'][0]['address_components'] as $comp) {
        //loop through each component in ['address_components']     
        foreach ($comp['types'] as $currType){          
       //for every type in the current component, check if it = the check

        if($currType == 'administrative_area_level_2'){
            //echo $comp['long_name'];
                $county = $comp['long_name'];
                    }           }
            }

使用具有完整地址的Google地理编码API可从JSON返回多个值
