有时候想在网页中向访客展示emlog博客的文章数量、评论数量、运行时间等信息，但emlog后台侧边栏没有提供相关的模块，因此需要博主自主添加博客统计信息代码。下面是整理的emlog网站信息统计代码，已在emlog 5.3.x上测试可用。
调用代码：
方法一：官方缓存类统计代码。优点：加载速度快；缺点：可能信息更新不及时。
把以下代码添加到当前使用的主题模板文件中，如side.php文件：
<?php $sta_cache = Cache::getInstance()->readCache('sta'); /必须添加/ ?>
- 文章总数： 篇
<li>评论总数：<?php echo $sta_cache['comnum_all']; ?> 条</li>
<li>闲言碎语：<?php echo $sta_cache['twnum']; ?>条</li>
<li>网站运行：<?php echo floor((time()-strtotime(20160423))/86400); ?> 天</li>
附：$sta_cache[‘参数’]中的参数可选如下：
lognum 游客可见日志总数
draftnum 草稿，也就是隐藏文件数量
comnum 未隐藏的评论数量
comnum_all 所有评论数量
hidecomnum 被隐藏的评论数量
twnum 微语数量
checknum 未审核的文章数量
方法二：自编函数，通过SQL语句查询相关数据。缺点：加载速度较缓存类慢；优点：实时显示
把下面的代码添加到主题的module.php文件中：
<?php//统计文章总数function count_log_all(){$db = MySql::getInstance();$data = $db->once_fetch_array("SELECT COUNT() AS total FROM " . DB_PREFIX . "blog WHERE type = 'blog'");return $data['total'];} //置顶文章数function count_log_top(){$db = MySql::getInstance();$data = $db->once_fetch_array("SELECT COUNT() AS total FROM " . DB_PREFIX .

"user WHERE role = 'writer'");return $data['total'];} //统计附件总数function count_att_all(){$db = MySql::getInstance();$data = $db->once_fetch_array("SELECT COUNT() AS total FROM " . DB_PREFIX . "attachment");return $data['total'];} //最后发表文章时间 function last_post_log(){$db = MySql::getInstance();$sql = "SELECT FROM " . DB_PREFIX . "blog WHERE type='blog' ORDER BY date DESC LIMIT 0,1";$res = $db->query($sql);$row = $db->fetch_array($res);$date = date('Y-n-j H:i',$row['date']);return $date;
