在PHP中获取数组数据

php arrays json api

在PHP中获取数组数据,php,arrays,json,api,Php,Arrays,Json,Api,我使用以下代码获取了JSON数据 $json = file_get_contents('http://api.openweathermap.org/data/2.5/weather?lat=35&lon=139'); $data = json_decode($json,true); print_r($data); foreach($data as $key => $datas){ $datas[$key]; } 这是解码后的json Array( [coord]

我使用以下代码获取了JSON数据

$json = file_get_contents('http://api.openweathermap.org/data/2.5/weather?lat=35&lon=139'); 
$data = json_decode($json,true);

print_r($data);
foreach($data as $key => $datas){
$datas[$key];
   }
这是解码后的json

   Array(
[coord] => Array
    (
        [lon] => 139
        [lat] => 35
    )

                [description] => scattered clouds
                [icon] => 03d
            )

    )

然后，我尝试使用Foreach方法显示数据，但无法正确显示

有人能帮我解决这个问题吗
  • $data由数组中的数组组成
  • 所以您需要正确地解析它
  • 使用嵌套的Foreach

              您可以轻松使用以下示例读取PHP数组：

              echo $data['coord']['lon'];
echo $data['coord']['lat'];
echo $data['sys']['message'];
echo $data['sys']['country'];
echo $data['sys']['sunrise'];
echo $data['sys']['sunset'];
.... And so on
