将名称插入表格中，并且在添加时间赋予名称添加：

<thead>
    <tr>
        <th><input type="checkbox" id="select-all-checkbox"></th>
        <th>名称</th> <!-- 新增 -->
        <th>网址</th>
        <th>状态</th>
    </tr>
</thead>
<tbody>
    <?php
    // 读取已保存的网址
    $url_file = 'urls.txt';
    if (file_exists($url_file)) {
        $urls = file($url_file, FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
    } else {
        $urls = array();
    }

    // 输出网址表格
    foreach ($urls as $index => $url) {
        $locked = strpos($url, 'locked:') === 0;
        $url = $locked ? substr($url, 7) : $url;
        echo '<tr>';
        echo '<td><input type="checkbox" name="url-checkbox" value="' . $index . '" ' . ($locked ? 'disabled' : '') . '></td>';
        echo '<td>' . ($locked ? '<span style="color: red;">[已锁定]</span>' : '') . '<a href="' . $url . '" target="_blank">' . $url . '</a></td>'; // 修改
        echo '<td>' . ($locked ? '锁定' : '正常') . '</td>';
        echo '</tr>';
    }
    ?>
</tbody>

将全选增加功能：

$(document).ready(function() {
    // 监听全选复选框点击事件
    $('#select-all-checkbox').click(function() {
        $('input[name="url-checkbox"]').prop('checked', $(this).prop('checked'));
    });

    // 监听复选框点击事件
    $('input[name="url-checkbox"]').click(function() {
        var checked = $('input[name="url-checkbox"]:checked');
        $('#select-all-checkbox').prop('checked', checked.length === $('input[name="url-checkbox"]').length);
    });

    // 其他代码...
});

将增加功能：

$(document).ready(function() {
    // 监听解锁按钮点击事件
    $('#unlock-btn').click(function() {
        var checked = $('input[name="url-checkbox"]:checked');
        if (checked.length > 0) {
            $('#unlock-dialog').show();
        }
    });

    // 其他代码...
});

优化完毕后的代码如下：
