Question

我发现它不会因为这些代码而受到赞誉，但如果有人可以通过以下编码帮助我显示天气，我将不胜感激。我将非常感激。

$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="sc")';
    $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>';

我只是想让这段代码显示一个特定地方的天气，其中包含一些我可以回音的变量

echo $city;
echo $temp;

像这样的东西。

非常感谢您宝贵的时间和善意的帮助

Answer 1

对于Php对象：

$phpObj =  json_decode($json);    // converting to object
echo $phpObj->property_name;

对于Php阵列：

$phpArr =  json_decode($json, true);    // converting to array
echo $phpArr['index'];

好吧，我得到它并分享代码，以便它可以用于寻找天气api的人

$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="sc")';
    $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 $phpObj->query->results->channel->location->city.' Weather  <br/>';
    echo 'Current: '.$phpObj->query->results->channel->item->condition->text.', ';
    echo sprintf("%0.0f", ($phpObj->query->results->channel->item->condition->temp - 32) * 5 / 9).'°C <br/>';

    echo $phpObj->query->results->channel->item->forecast[0]->day.': ';
    echo $phpObj->query->results->channel->item->forecast[0]->text.', ';
    echo '<small>'.sprintf("%0.0f", ($phpObj->query->results->channel->item->forecast[0]->low - 32) * 5 / 9).'Min°C - </small>';
    echo '<small>'.sprintf("%0.0f", ($phpObj->query->results->channel->item->forecast[0]->high - 32) * 5 / 9).'Max°C </small><br/>';

    echo $phpObj->query->results->channel->item->forecast[1]->day.': ';
    echo $phpObj->query->results->channel->item->forecast[1]->text.', ';
    echo '<small>'.sprintf("%0.0f", ($phpObj->query->results->channel->item->forecast[1]->low - 32) * 5 / 9).'Min°C - </small>';
    echo '<small>'.sprintf("%0.0f", ($phpObj->query->results->channel->item->forecast[1]->high - 32) * 5 / 9).'Max°C </small><br/>';
