Question

我使用雅虎天氣API來獲取在PHP雅虎天氣API JSON響應，我需要在我的網站

當前溫度=（攝氏溫度）（即[項目] [「條件」，顯示如下信息] [ '溫度']）

多雲（即[項目] [ '狀態'] [ '文本']）

<?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>'; 



?> 

這是JSON響應

Answer 1

達到你想呼應

echo $phpObj->query->results->channel->item->condition->text

Answer 2

這將返回今天的everage臨時對象和條件

function getCurrentTemp($obj){ 
    return (($obj->query->results->channel->item->forecast[0]->high)+($obj->query->results->channel->item->forecast[0]->low))/2; 
} 

function getCurrentCondition($obj){ 
    return $obj->query->results->channel->item->forecast[0]->text; 
} 

function fahrenheit_to_celsius($given_value) 
{ 
    $celsius=5/9*($given_value-32); 
    return $celsius ; 
} 

echo fahrenheit_to_celsius(getCurrentTemp($phpObj))." ".getCurrentCondition($phpObj);
