继承了我的观点，但它说未知的loan_id 在我的foreach中，我不知道如何使用每个元素的数组中的数组访问数组

                              <?php foreach($loans as $row) : ?>
                                <tr>
                                    <td class="text-center"><?= $loans['loan_id'] ?></td>
                                    <td class="text-center"></td>
                                    <td class="text-center"></td>
                                    <td class="text-center"></td>
                                    <td class="text-center">
                                        <td class="text-center"></td>
                                        <tr>
                                            <td class="text-center"></td>
                                            <td class="text-center"></td>
                                            <td class="text-center"></td>
