Question

我正在使用代码从Excel工作表中导入数据，当我第一次导入工作表它将值插入mysql时，它工作正常，但是当我更改某些值时在工作表上并尝试导入数据，它不会更新任何东西。

                    <ul class="nav paket-navbar">
                        <li <?php if ($_controller=="dashboard")echo "class='active'"?>><a href="<?php echo base_url('dashboard')?>"><i class="fi flaticon-home"></i> Dashboard</a></li>
                        <li <?php if ($_controller=="book")echo "class='active'"?>><a href="<?php echo base_url('book')?>"><i class="fi flaticon-copy"></i> Book</a></li>
                        <li <?php if ($_controller=="settings")echo "class='active'"?>><a href="<?php echo base_url('settings')?>"><i class="fi flaticon-setting"></i> Settings</a></li>
                        <li><a href="<?php echo base_url('login/logout')?>" onclick="return signOut();"><i class="fi flaticon-caret-left"></i> Sign out</a></li>
                    </ul>
                </div>

如何使用不同的数据更新多行？
