试图从谷歌股票 api 中提取一些数据。所以只是试图提取它。
$t=time();
echo(date("H:i",$t))."<br><br>";
$xml="http://www.google.com/ig/api?stock=KNEBV&stock=FUM1V";
$xml = json_decode(json_encode((array) simplexml_load_file($xml)), 1);
echo '<pre>';
print_r($xml);
echo '</pre>';
?>
这给了我下面的输出。但我似乎无法获得任何价值。我迷失在数据中，不知道从哪一端开始。
我假设$xml-> finance[0]->symbol会给我“ FUM1V ”，而$xml-> Finance[1]->symbol会给我KNEBV但无论我尝试什么组合，我都会得到空白。好的，这可能是一个不好的例子，但在翻译中丢失了。
关于如何“循环”并打印每个符号和一些值的任何想法？
