javascript - 如何在 php var OpenWeatherMap 中获取第二行 js 数据

Question

这是我的代码

$city="Delhi";
$country="IN"; 
$url="http://api.openweathermap.org/data/2.5/weather?q=".$city.",".$country."&units=metric&dt=1461412800&cnt=5&lang=en&APPID=xxxxx";
$json=file_get_contents($url);
$data=json_decode($json,true);

它返回这个；

"weather":[
                 {"id":520,"main":"Rain","description":"light intensity shower rain","icon":"09d"},
                 {"id":500,"main":"Rain","description":"light rain","icon":"10d"},
                 {"id":701,"main":"Mist","description":"mist","icon":"50d"}
              ],

如何使用 php 获取第二行数据？

有第一行；$weather = $data['weather'][0]['description'];

Answer 1

如果你想要第二行，只需这样抓住它：

$weather = $data['weather'][1]['description'];

或者，如果您的目标是列出所有结果，只需使用foreach。
