JSONデータを使用してOpenWeatherMapから7日間の予測を取得するにはどうすればよいですか？

Question

私はWeatherアプリケーションを作成しようとしています。私は現在の条件を取得する方法を知っていますが、正直なところ私はあまりJSONを知らない。 OpenWeatherMapから7日間の予測を取得する方法はわかりません。私は考えることができるすべてを試しましたが、何も動いていません。私はPHPからそれを取得しようとしています。私は本当にそれがどのように動作するか、正直には分かりません。誰かが助けることができれば、それは高く評価されるでしょう。

['city'] ['name'];を入力します。例のように。

私のPHPコード：

<?php 
$city="London"; 
$country="UK"; 
$url="http://api.openweathermap.org/data/2.5/forecast/daily?q=".$city.",".$country."&units=metric&cnt=7&lang=en&appid=c0c4a4b4047b97ebc5948ac9c48c0559"; 
$json=file_get_contents($url); 
$data=json_decode($json,true); 
$data['city']['name']; 
?> 

は、ここでJSONデータである：これは本当にばかな質問ですが、任意の助けをいただければ幸い場合

申し訳ありませんが、ありがとう！

あなたは実際に次の6日間の情報を得ています。完全な配列を見て、あなたが完全な結果で見ることができるように

print_r($data); 

を行う例えば、6日のtheres：

[5] => Array 
      (
       [dt] => 1462964400 
       [temp] => Array 
        (
         [day] => 19.18 
         [min] => 13.92 
         [max] => 19.18 
         [night] => 14.57 
         [eve] => 18.88 
         [morn] => 13.92 
        ) 

       [pressure] => 1004.19 
       [humidity] => 0 
       [weather] => Array 
        (
         [0] => Array 
          (
           [id] => 500 
           [main] => Rain 
           [description] => light rain 
           [icon] => 10d 
          ) 

        ) 

       [speed] => 3.24 
       [deg] => 180 
       [clouds] => 22 
       [rain] => 2.13 
      ) 

だから、あなたが何をする必要があるかのforeach

foreach($data['list'] as $day => $value) { 
    echo "Max temperature for day " . $day . " will be " . $value[temp][max] . "<br />" ; 
} 

です

これが返されます：

Max temperature for day 0 will be 21.87 
Max temperature for day 1 will be 23.03 
Max temperature for day 2 will be 24.53 
Max temperature for day 3 will be 23.59 
Max temperature for day 4 will be 22.88 
Max temperature for day 5 will be 19.18 
Max temperature for day 6 will be 14.84 

これが役立つことを願っています！
