am new to programming. Am trying to display a text after 5 rows from the database. thanks in advance

my php query:

$post_status= "Published";
$stmt = $mysqli->prepare("SELECT * FROM user_post WHERE status = ? GROUP BY post_id ORDER BY post_id DESC");

$stmt->bind_param('s', $post_status);

        $stmt->execute();

        $result = $stmt->get_result();

        if ($result->num_rows > 0) {
          while($row = $result->fetch_assoc()) {
            //display the outcome here
