我希望这不会太复杂！感谢您的帮助！谢谢！

试试这个：

$prevDate = null;
while ($row = $result->fetch_assoc()) {
    $mark = false;
    if ($row['postdate'] != $prevDate) {
        $mark = true;
        $prevDate = $row['postdate'];
    }
    ?>
    <? if ($mark) { ?>
        <div class="content">
        <? } ?>
        <? if (!empty($row['image'])) { ?>
            <img src="/images/thumbs/<?= $row['image'] ?>">
        <? } ?>

        <? if ($mark) { ?>
            <h1><?= $row['postdate']; ?></h1>
        <? } ?>
        <h3><?= $row['title']; ?></h3>   
        <p><?= $row['venue'] . " | " . $row['city'] . " | " . $row['time'] . " | " . $row['cost']; ?></p>
        <? if ($mark) { ?>
        </div>
        <div class="horizontal-line"></div>
    <? } ?>
<? } ?>

$prevDate=null；
而（$row=$result->fetch_assoc（））{
$mark=false；
如果（$row['postdate']！=$prevDate）{
$mark=true；
$prevDate=$row['postdate']；
}
?>

多亏“khomyakoshka”带领我朝着正确的方向前进，我才得以成功

…现在我不是说这是最好的方法，但它是有效的

<?php   
$prevDate = null;
$i = 0;
    while ($row = $result->fetch_assoc()) {
        $mark = false;
        if ($row['postdate'] != $prevDate) {
            $mark = true;
            $prevDate = $row['postdate'];
        }

        if ($mark && $i == 0) {
?>
            <div class="content">
<?php
        } elseif ($mark) {
?>          
            <div class="clear"></div>
            </div>
            <div class="horizontal-line"></div>
            <div class="content">
<?php           
        }

        if (!empty($row['image'])) { 
?>
            <img src="/images/thumbs/<?= $row['image'] ?>">
<?php
        }

        if ($mark) { ?>
            <h1><?php echo $row['postdate']; ?></h1>
<?php
        }
?>
        <h3><?php echo $row['title']; ?></h3>   
        <p><?php echo $row['venue'] . " | " . $row['city'] . " | " . $row['time'] . " | " . $row['cost']; ?></p>
<?php
                $i++;
                }
            ?>
            <div class="clear"></div>
            </div>

它做错了什么？是水平线吗？您的示例没有提到带有

class=“content”

的项目，因此我无法判断这是否正确。我认为我的示例是这样做的……但它做错了的是包装每个“事件”（H3标记和P标记）在后面是水平规则…我希望它用相同的日期包装所有的“事件”，然后用一条水平线来添加视觉分隔。这更接近了！…我想我现在可能能够解决它。请看一个例子。它满足了你的需要。我将接受你的答案，因为你已经回答了这个问题，我举个例子st需要对其进行一些修改以适合我的代码。再次感谢！我将更经常地使用此位置。欢迎使用Stackoverflow=）
