emlog博客系统网站信息统计调用代码分享

       其实在emlog网站中想更能直观的展现博客得信息内容，由于它官方没有提供特定的模块代码，因此需要自己添加一下查询代码。 以下是别人整理的emlog博客网站调用的统计信息代码。具体可以通过两种方法来实现，各有优缺点，根据具体环境，酌情使用。

使用方法:添加到当前使用的主题模板文件中，module.php输出部分，或侧边栏输出部分，官方缓存类统计代码。优点：加载速度快；缺点：信息更新不如直接查询准确

<?php $sta_cache = Cache::getInstance()->readCache('sta'); /*必须添加*/ ?>
    <ul>
        <li>文章数：<?php echo $sta_cache['lognum']; ?> 篇</li>
        <li>评论数：<?php echo $sta_cache['comnum_all']; ?> 条</li>
        <li>未审核评论数：<?php echo $sta_cache['comnum']; ?> 条</li>
        <li>隐藏评论数：<?php echo $sta_cache['hidecomnum']; ?> 条</li>
        <li>草稿数：<?php echo $sta_cache['draftnum']; ?> 条</li>
        <li>未审核文章数：<?php echo $sta_cache['checknum']; ?> 条</li>
        <li>微语数：<?php echo $sta_cache['twnum']; ?>条</li> /*微语数在emlog pro版中更换为笔记，并且官方没在提供此类缓存*/
        <li>网站运行：<?php echo floor((time()-strtotime(20160423))/86400); ?> 天</li>  
    </ul>

添加到当前使用的主题模板文件中

自查函数，通过SQL语句查询相关数据。缺点：此类查询过多导致加载速度缓慢；优点：实时显示
