我正在一个告白网站上工作，并且在该网站上有一个“本周热门”部分，其中显示了本周的3个最喜欢的告白，并按最喜欢的顺序在水平滑块中显示了这些告白。最喜欢的，第二最喜欢的，第三最喜欢的表白。我想做的就是在每个数字上分别添加＃1，＃2，＃3号，但是我无法实现这一点，因为我只设置了一个div的样式，网站自动创建了另外两个，并向其添加了表白。 >
这是我用来显示它们的php + html代码：
<div class="sidebox">
<?php
$select = "SELECT confessions.confessId,
(IFNULL(confessions.firstName, '')) AS firstName,
confessions.confessText,
DATE_FORMAT(confessions.postDate,'%b %d %Y %h:%i %p') AS postDate,
hasImage,
UNIX_TIMESTAMP(confessions.postDate) AS orderDate,
confessions.isActive,
(SELECT COUNT(*) FROM views WHERE views.confessId = confessions.confessId ) as totalViews,
(SELECT COUNT(*) FROM likes WHERE likes.confessId = confessions.confessId ) as totalLikes,
(SELECT COUNT(*) FROM dislikes WHERE dislikes.confessId = confessions.confessId ) as totalDislikes
FROM
confessions
WHERE isActive = 1
ORDER BY totalViews DESC , orderDate DESC limit 3";

我尝试了所有方法，这是我拥有的最佳解决方案，但是我不知道应该在if, elseif, else中放入什么，我需要将＃1放在第一，第二放在第二， ＃3在第三次坦白。因此，我需要像这样的东西，但是不需要我手动插入>喜欢的东西。
<?php if ($row['totalLikes'] > '11') { echo "#1"; } elseif ($row['totalLikes'] > '5') { echo "#2"; } else { echo "#3"; }?>
请访问我的网站，该网站仍在开发中，但请查看右侧的“每周精选”，您将了解我的实际需求：http://confessions.byethost31.com
最终：
<?php $i = 1; ?>
<?php
echo '#'.$i;
$i++;
?>
答案 0 :(得分：0)
最简单的方法是创建一个随每次while迭代递增的变量。
$i = 1; // set initial value
while ($row = mysqli_fetch_assoc($resss)) {
echo 'This number will grow by 1 for every row - '.$i;
$i++; // this is equal to $i = $i + 1; so will increment by 1 every time.
}
编辑：
与其尝试假设总喜欢的人数，不如按总喜欢的人数进行排序（将最喜欢的对象放在第一位并分配此＃1）会更容易。
ORDER BY totalLikes DESC, totalViews DESC, orderDate DESC
然后您可以使用
echo '#'.$i;
要显示数字的位置，可以执行此操作，因为您有LIMIT 3，因此仅显示前3个。
