我使用mysqli_fetch_assoc（）以递减的顺序获取数组，并以不同的方式获取。我如何纠正它？

Question

I used mysqli_fetch_assoc function to fetch the rows in a decreasing order but when I echo the associative array of table "posts"(there are only three rows in the posts table- post 1,post 2 , post 3)

it prints in this manner:( I have added a screenshot of this output )

post 3 (edit/delete)

post 3 (edit/delete)
post 2 (edit/delete)

post 3 (edit/delete)
post 2 (edit/delete)
post 1 (edit/delete)

I wanted it to print in this manner:

post 3 (edit/delete)
post 2 (edit/delete)
post 1 (edit/delete)

Here is my code:

    <?php
    $db = mysqli_connect("localhost", "root", "", "myblog");
    $sql = "SELECT * FROM posts ORDER BY id DESC";
    $res = mysqli_query($db, $sql) or die(mysqli_error($db));
    $count = mysqli_num_rows($res);
    $posts = "";

    if ($count > 0) {
      while ($row = mysqli_fetch_assoc($res)) {
        $id = $row['id'];
        $title = $row['title'];
        $content = $row['content'];
        $date = $row['date'];


        $admin = "
               <div>
               <a href='del_post.php?pid=$id'>DELETE </a>
               <a href='edit_post.php?pid=$id'>EDIT</a>
               </div>
               ";
        $posts .= "<div><h4>$title</h4><h3>$date</h3><p>$content</p>$admin</div>";

        echo $posts;
      }
    } else {
      echo "there is nothing to show";
    }

    ?>

Thanks.

I think the the problem is in this line,

while ($row = mysqli_fetch_assoc($res)

need to change $res for $count instead.
