Mysql Database Row值在ph​​p中提取问题

Question

我试图通过选择查询获取数据库中存在的数据。但有些东西是错误的，数据是由这个正确提取的。我没有得到它。让我知道我做错了什么。如果你能告诉我在这里需要做什么，我会有所帮助。我已经正确地访问了行。但它仍然没有提取数据。

Use a proper IDE like NetBeans,Sublime Text for writing php codes.These IDE will show the error ,warning indications.In your case,you missed one closing bracket.Use the below code.

<?php

$query = "SELECT * FROM notification ORDER BY noti_id DESC LIMIT 5";
                                $result = mysqli_query($connect, $query);
                                $output = '';
                    if(mysqli_num_rows($result) > 0)
                      {
                          while($row = mysqli_fetch_array($result))
                       {
                        $output .= '

                            <div class="c-cart-menu-close">
                                <a href="#" class="c-theme-link"></a>

                        <img src="assets/base/img/content/shop2/12.jpg" />
