how to fetch yahoo weather api json response in php

Question

I am using yahoo weather API , I need to display the following info in my website

Current Temperature = (in Celsius)(ie [item] ['condition'] ['temp'])

Mostly Cloudy (ie [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>';



?>

This is the Json Response

Answer 1

到达要回显的对象

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

Answer 2

this will return the everage temp of today and the conditions

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);
