我正在学习如何解析json文件...无法弄清楚我的错误..在图上绘制这些数据

$url="https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.historicaldata%20where%20symbol%20in(%22TATASTEEL.NS%22)%20and%20startDate%3D%222015-07-01%22%20and%20endDate%3D%222015-07-30%22&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=";

$output = file_get_contents($url);

$jdecode=json_decode($output,true);

foreach ($jdecode[query][results][quote][Open] as $key => $value) {
    # code...
    echo $key." : ".$value."<br>";
}

例如：当我在yql console中输入此查询时：

从yahoo.finance.historicaldata中选择*，其中符号位于（＆＃34; TATASTEEL.NS＆＃34;）和startDate =＆＃34; 2014-03-01＆＃34;和endDate =＆＃34; 2015-03-30＆＃34;

我得到像这样的json链接：

＆＃39; https://query.yahooapis.com/v1/public/yql?q=select%20 *％20from％20yahoo.finance.historicaldata％20where％20symbol％20英寸20％（％22TATASTEEL.NS％22）％20于是％20startDate％20％3D％20％222014- 03-01％22％20于是％20endDate％20％3D％20％222015-03-30％22安培;格式= JSON＆安培;诊断=真安培; ENV =商店％3A％2F％2Fdatatables.org％2Falltableswithkeys＆安培;回调=＆＃ 39;

我如何解析这个json ......
