这是我用来从雅虎财经股票报价中获取数据的脚本。但我在这里遇到问题..并且无法从我得到的答案中找到解决方案。 PHP脚本是......
<?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;
}
}
?>
我打印会话的显示部分或正文部分是......

但我从上面得到的结果是......

这只是$ yql_query =“select * from ...'PLN12.NYM','PAK12.NYM','的'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')";
来自雅虎网站的雅虎财经报价的XML输出是。

答案 0 :(得分:0)
您没有正确存储数据。你想要打印$ _SESSION ['Ask_2'],但它永远不会被设置!相反,在循环中你会覆盖$ _SESSION ['Ask'] - 您可能想要做的是获取引号,然后将数据存储在$ _SESSION [$ symbol] ['Ask']中。
实际上我建议使用另一个数组来编译数据,然后在其中设置一个包含该数组的会话变量,而不是不断更新会话变量。
你想要一个像这样的循环:
foreach($phpObj->query->results->quote as $quote){
$mydata[$quote->Symbol]['Ask'] = $quote->Ask;
然后,当您显示结果时,请显示foreach ($mydata as $quote)
而不是$_SESSION
。最后,如果您想将所有内容存储在会话中,您可以说$_SESSION['quotedata'] = $mydata
。

我还建议你把它显示在一个表而不是一个。
中使用下面的解决方案,您只需在符号列表中添加/减去值,表格就会自动更改。
即,如果你改变了
$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')";
那么你的桌子只有一个额外的行,用于股票代码BOOM。 我测试了这个并且它有效。
以下是您的数据收集部分,修正了Ansari:
$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;
}
}
以下是表格形式的输出:
<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>
