这是我用来从雅虎财经股票报价中获取数据的脚本。但我面临的问题在这里..并不能找到我得到的答案的解决方案。 PHP脚本是...yql使用php从XML获取的数据覆盖其他金融股票代码的值

<?php 
session_start(); 

$yql_base_url = "http://query.yahooapis.com/v1/public/yql"; 
$yql_query = "select * from yahoo.finance.quotes where symbol in ('XAUUSD=X','XAGUSD=X','PLN12.NYM','PAK12.NYM','USDCAD=X')"; 
$yql_query_url = $yql_base_url . "?q=" . urlencode($yql_query); 
$yql_query_url .= "&env=http://datatables.org/alltables.env"; 
$yql_query_url .= "&format=json"; 
$session = curl_init($yql_query_url); 
curl_setopt($session, CURLOPT_RETURNTRANSFER,true);  
$json = curl_exec($session); 
$phpObj = json_decode($json); 
if(!is_null($phpObj->query->results)){ 
} 
if(!is_null($phpObj->query->results)){ 
    foreach($phpObj->query->results->quote as $quotes){ 
     $_SESSION['Ask'] = $quotes->Ask; 
     $_SESSION['Bid'] = $quotes->Bid; 
     $_SESSION['AskRealtime'] = $quotes->AskRealtime; 
     $_SESSION['BidRealtime'] = $quotes->BidRealtime; 
     $_SESSION['LastTradeDate'] = $quotes->LastTradeDate; 
     $_SESSION['LastTradePriceOnly'] = $quotes->LastTradePriceOnly; 
     $_SESSION['LastTradeTime'] = $quotes->LastTradeTime; 
    } 
} 
?>

和显示部分或身体的一部分，其中i打印会话...

<body> 
    <div> 
    <ul> 
    <li>Gold Price</li> 
    <li><?php echo $_SESSION['Ask'];?></li>

    <li><?php echo $_SESSION['BidRealtime_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeDate_3'];?></li> 
    <li><?php echo $_SESSION['LastTradePriceOnly_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeTime_3'];?></li> 
    </ul> 
    <ul> 
    <li>Palladium Price</li> 
    <li><?php echo $_SESSION['Ask_3'];?></li> 
    <li><?php echo $_SESSION['Bid_3'];?></li> 
    <li><?php echo $_SESSION['AskRealtime_3'];?></li> 
    <li><?php echo $_SESSION['BidRealtime_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeDate_3'];?></li> 
    <li><?php echo $_SESSION['LastTradePriceOnly_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeTime_3'];?></li> 
    </ul> 
    <ul> 
    <li>USD to CAD</li> 
    <li><?php echo $_SESSION['Ask_3'];?></li> 
    <li><?php echo $_SESSION['Bid_3'];?></li> 
    <li><?php echo $_SESSION['AskRealtime_3'];?></li> 
    <li><?php echo $_SESSION['BidRealtime_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeDate_3'];?></li> 
    <li><?php echo $_SESSION['LastTradePriceOnly_3'];?></li> 
    <li><?php echo $_SESSION['LastTradeTime_3'];?></li> 
    </ul> 
    </div> 
    </body>

但结果我从上面得到的是..
1.0015
1.0005
5/11/2012
1.001下午5点55分

这是$ yql_query =“select * from ...'PLN12.NYM'，'PAK12.NYM'，'USDCAD = X'）的会话输出'USDCAD = X'”

查询是..

$yql_query = "select * from yahoo.finance.quotes where symbol in ('XAUUSD=X','XAGUSD=X','PLN12.NYM','PAK12.NYM','USDCAD=X')";

和XML输出雅虎财经引述雅虎网站。

你无法正常存储数据。你想打印$ _SESSION ['Ask_2']但它从未设置！相反，在循环中，您一直覆盖$ _SESSION ['Ask'] - 您可能想要做的是获取引号符号，然后将数据存储在$ _SESSION [$ symbol] ['Ask']中。

事实上，我会建议使用另一个数组来编译数据，然后设置一个单一的会话变量与其中的数组，而不是连续更新会话变量。

你想拥有这样一个循环：

foreach($phpObj->query->results->quote as $quote){ 
    $mydata[$quote->Symbol]['Ask'] = $quote->Ask;

然后，当你从foreach ($mydata as $quote)而不是$_SESSION显示结果，显示。最后，如果你想在会话中存储所有内容，你可以只说$_SESSION['quotedata'] = $mydata。

我也建议你将它显示在表格中而不是在。

使用下面的解决方案，您可以添加/减去符号列表中的值，并且表格会自动更改。

也就是说，如果您改变

$yql_query = "select * from yahoo.finance.quotes where symbol in ('XAUUSD=X','XAGUSD=X','PLN12.NYM','PAK12.NYM','USDCAD=X')";

到

$yql_query = "select * from yahoo.finance.quotes where symbol in ('XAUUSD=X','XAGUSD=X','PLN12.NYM','PAK12.NYM','USDCAD=X','BOOM')";

那么你的表将只拥有股票代码BOOM一个附加行。 我测试了这个，它的工作原理。

这是你的数据收集部分，与校正安萨里提出：

$yql_base_url = "http://query.yahooapis.com/v1/public/yql"; 
$yql_query = "select * from yahoo.finance.quotes where symbol in ('XAUUSD=X','XAGUSD=X','PLN12.NYM','PAK12.NYM','USDCAD=X')"; 
$yql_query_url = $yql_base_url . "?q=" . urlencode($yql_query); 
$yql_query_url .= "&env=http://datatables.org/alltables.env"; 
$yql_query_url .= "&format=json"; 
$session = curl_init($yql_query_url); 
curl_setopt($session, CURLOPT_RETURNTRANSFER,true);  
$json = curl_exec($session); 
$phpObj = json_decode($json); 
if(!is_null($phpObj->query->results)){ // this does nothing. remove it? 
} 

if(!is_null($phpObj->query->results)){ 
    foreach($phpObj->query->results->quote as $quotes){ 
     $mydata[$quotes->Symbol]['Ask'] = $quotes->Ask; 
     $mydata[$quotes->Symbol]['Bid'] = $quotes->Bid; 
     $mydata[$quotes->Symbol]['AskRealtime'] = $quotes->AskRealtime; 
     $mydata[$quotes->Symbol]['BidRealtime'] = $quotes->BidRealtime; 
     $mydata[$quotes->Symbol]['LastTradeDate'] = $quotes->LastTradeDate; 
     $mydata[$quotes->Symbol]['LastTradePriceOnly'] = $quotes->LastTradePriceOnly; 
     $mydata[$quotes->Symbol]['LastTradeTime'] = $quotes->LastTradeTime; 
    } 
}

这里是表格形式输出：

<table border="1"> 
<thead> 
<tr> 
<?php 
$head = array('Symbol','Ask','Bid','Ask Realtime','Bid Realtime','Last Trade Date','Last Trade Price','Last Trade Time'); 
foreach($head as $value) { 
    echo '<th>' . $value . '</th>'; 
} 
?> 
</tr> 
</thead> 
<tbody> 
<?php 
foreach($mydata as $symbol=>$attrib) { 
    echo '<tr>'; 
    echo '<td>' . $symbol . '</td>'; 
    foreach($attrib as $val) { 
     echo '<td>' . $val . '</td>'; 
    } 
    echo '</tr>'; 
} 
?> 
</tbody> 
</table>
