在新版本移除在线状态和加载时间需要的可以自行添加

在footer.php合适的位置加入

<p><?php _e('页面加载耗时'); ?><?php echo timer_stop();?> </p>
<p>💻️ <?php $this->author(); ?> <?php get_last_login(1); ?> 在线</p>

在functions.php最后加入

/***
 * 在线状态
 */
function get_last_login($user){
    try {
        $user   = '1'; 
        $now    = time();

        $prefix = $db->getPrefix();
        $row = $db->fetchRow($db->select('activated')->from('table.users')->where('uid = ?', $user));
        if ($row) {
            echo Typecho_I18n::dateWord($row['activated'], $now);
        } else {
            echo '博主一直在这里';
        }
    } catch (Exception $e) {
        error_log('Error in get_last_login: ' . $e->getMessage());
        echo '博主一直在这里';
    }
}
