現在、データベースから2つの異なるアイテムを取得する必要があるデータベースへの単純なクエリがあります。データベースを見つけて取得していることは知っていますが、1 つのレコードしか取得していないようです。

私の質問は次のとおりです。以下のコードがデータベースから 1 つ以上のレコードを取得しないのはなぜですか?

<?php

include('config.php');

$sql = "SELECT * FROM sponsoredBackground ORDER BY id DESC LIMIT 3";
$retval = mysql_query( $sql, $con ); 
if(! $retval )
{
  die('Could not get data: ' . mysql_error());
}

echo "<div id=\"headerSlider\">";

while($row = mysql_fetch_array($retval))
{

?>
<div class="headerContainer" style="background: transparent url('/images/<?php echo $row['imageName']; ?>') 0 0 no-repeat;">
        <div class="headerLeftContent">
            <div class="sponsoredBackground">
                <a href="http://<?php echo $row['url']; ?>">        
                    View this Opportunity
                </a>

featuredEvents.phpページに含めると、いくつかのSQL処理が行われるだけでなく、変数が含まれていないことを再確認するだけである可能性があります$retval。
