php - 如何在 php 中获取 yahoo weather api json 响应

Question

我正在使用 yahoo weather API ，我需要在我的网站上显示以下信息

当前温度 =(摄氏度)(即 [item] ['condition'] ['temp'])

大部分多云(即 [item] ['condition'] ['text'])

<?php
    $BASE_URL = "http://query.yahooapis.com/v1/public/yql";

    $yql_query = 'select * from weather.forecast where woeid in (select woeid from geo.places(1) where text="amaravathi")';
    $yql_query_url = $BASE_URL . "?q=" . urlencode($yql_query) . "&format=json";

    // Make call with cURL
    $session = curl_init($yql_query_url);
    curl_setopt($session, CURLOPT_RETURNTRANSFER,true);
    $json = curl_exec($session);
    // Convert JSON to PHP object
    $phpObj =  json_decode($json);
    echo '<pre>';print_r($phpObj).'<pre>';



?>

这是 Json 响应
