while循环只显示1个结果

Question

我目前正在研究一个搜索系统，我希望显示所有具有2个列名称的行，问题是，当我在数据库中有2个时，我的while循环只显示1行。我一直在努力工作几个小时，但我无法得到它。我得到的唯一输出是最后价格。

<?php
include_once("inc/head.php");
include_once("inc/db.php");
$leave = $_POST['departure'];
$come = $_POST['destination'];
$leavedate = $_POST['leavedate'];
$comedate = $_POST['comedate'];
$sql = "select * from flights where departure = '$leave' and destination ='$come'";
$result = $db->query($sql);
$row = $result->fetchObject();
$price = $row->price;
$mostflights = $row->departure;
$mostcomings = $row->destination;
?>

<div>
    <ul class="flights">
        <?php
       while($row = $result->fetchObject())
        $price = $row->price;
        $mostflights = $row->departure;
        $mostcomings = $row->destination;
       { ?>

        <li>
            <h3><?php echo  $mostflights; ?></h3>
            <h2><?php echo  $mostcomings; ?></h2>
            <h2><?php echo  $price; ?></h2>
        </li>
        <?php
      }
  ?>
    </ul>
</div>

在第10行删除此块

$row = $result->fetchObject();
$price = $row->price;
$mostflights = $row->departure;
$mostcomings = $row->destination;
