我目前对数据库有一个简单的查询，它应该从我的数据库中检索 2 个不同的项目。我知道它正在查找数据库并检索，但它似乎只检索 1 条记录。

我的问题是：为什么下面的代码从数据库中提取的记录不超过 1 条？

<?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>
            </div>

很可能featuredEvents.php您在页面上包含一些 sql 内容，只需仔细检查并确保它没有变量$retval。
