php解析json數據

從來沒有這樣做過，並且對格式和如何訪問特定變量感到困惑。php解析json數據

結果：

$result = json_decode($result); 
print_r($result);

是：

stdClass Object 
(
    [input] => stdClass Object 
     (
      [address_components] => stdClass Object 
       (
        [number] => 1109

       ) 

      [formatted_address] => 1109 N Highland St, Arlington, VA 22201 
     ) 

    [results] => Array 
     (

     )

我如何可以訪問緯度和經度值？由於混合了對象和數組，因此我感到困惑。我從來沒有用這種方式與PHP的JSON合作...這是一個地理編碼api，返回JSON格式。

我基本上想要做一些類似$lat = $result['results'][0]['location']['lat'];等等。

使用類型轉換，將其轉換成對象 –

你必須json_decode使用true作爲第二個參數，以便輸出將是正常的PHP數組不stdclass陣列（這樣就可以用你的方法，你正在嘗試什麼）

所以做象下面這樣： -

$result = json_decode($result,true); 

echo $lat = $result['results'][0]['location']['lat']; 
echo $lng = $result['results'][0]['location']['lng'];

注： -

1.根據您目前的格式，也可以得到數據如下圖所示： -

echo $lat = $result->results[0]->location->lat; //using object approach 
echo $lng = $result->results[0]->location->lng; //using object approach

2.使用foreach()讓所有lat-lng記錄。

foreach($result->results as $val) { //if using stdclass array 
    echo "Latitude = ".$val->location->lat; 
    echo "Longitude = ".$val->location->lng; 
}

或者： -

foreach($result['results'] as $val) {//if using normal array 
    echo "Latitude = ".$val['location']['lat']; 
    echo "Longitude = ".$val['location']['lng']; 
}

知道它是一些簡單的我失蹤了......這就是我一直在尋找...謝謝！ – user756659

@ user756659很高興幫助你:) :) –

使用第二個參數爲轉換所有對象數組爲真。否則，你可以得到這樣的值。

$result->results[0]->location->lat; 
$result->results[0]->location->lng;

這是'lng'不''長'。現在+1，因爲你也是正確的。 –

您可以從結果存取緯度經度如下

$result = json_decode($result); 
echo $result->results[0]->location->lat; 
echo $result->results[0]->location->lng;

我可以看到，從你的榜樣，你有多個記錄來獲取。使用foreach()打印細節

$result = json_decode($result); 
foreach($result->results as $value) { 
    echo "Lat--",$value->location->lat; //using object 
    echo "Long--",$value->location->lng; 
}
