php - PHPループですべてのxml配列を取得する方法

Question

PHPセッションでxmlデータを取得し、divに出力しました。クエリのすべてのデータを印刷したい..

<?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;
  }  
}  
?>

1 つの結果のみが出力されます..
1.0015
1.0005
5/11/2012
1.001 5:55pm

しかし、私はこのようなことをしたい

<body>
<div>
<ul>
<li>Gold Price</li>
<li><?php echo $_SESSION['Ask'];?></li>
<li><?php echo $_SESSION['Bid'];?></li>
<li><?php echo $_SESSION['AskRealtime'];?></li>
<li><?php echo $_SESSION['BidRealtime'];?></li>
<li><?php echo $_SESSION['LastTradeDate'];?></li>
<li><?php echo $_SESSION['LastTradePriceOnly'];?></li>
<li><?php echo $_SESSION['LastTradeTime'];?></li>
</ul>
<ul>
<li>Silver Price</li>
<li><?php echo $_SESSION['Ask_2'];?></li>
<li><?php echo $_SESSION['Bid_2'];?></li>
<li><?php echo $_SESSION['AskRealtime_2'];?></li>
<li><?php echo $_SESSION['BidRealtime_2'];?></li>
<li><?php echo $_SESSION['LastTradeDate_2'];?></li>
<li><?php echo $_SESSION['LastTradePriceOnly_2'];?></li>
<li><?php echo $_SESSION['LastTradeTime_2'];?></li>
</ul>
<ul>
<li>Platinum 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>
</div>
</body>

それらのすべての結果を印刷したい

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

XMLは次のようになります

ここでは配列が役立つはずだと思います。

<?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)){
    $_SESSION['Ask']=array();
    $_SESSION['Bid']=array();
    $_SESSION['AskRealtime']=array();
    $_SESSION['BidRealtime']=array();
    $_SESSION['LastTradeDate']=array();
    $_SESSION['LastTradePriceOnly']=array();
    $_SESSION['LastTradeTime']=array();

    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;
  }  
}
?>

これで、セッション配列を反復処理できます。

注：[]各セッション変数を配列として宣言しないと、が機能しない理由はわかりません。お役に立てば幸いです。
