EMLOG网站信息统计代码(全)

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*/ ?>
<ul>
 <li>文章总数：<?php echo $sta_cache['lognum']; ?> 篇</li>
 <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> 
</ul>

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：
