今天有站长问冬镜：Emlog程序想要使网站统计到整站的文章数据、用户数据、建站时间、标签、友链等信息，是需要直接写代码就行还是需要插件？冬镜这里可以直接告诉大家，不管你是使用插件还是代码都可以实现网站整站数据统计。那么，实现网站信息统计难吗？
网站信息统计
Emlog实现网站信息统计采用代码的方式来实现是很简单的，就算你不特别懂代码，只要跟着冬镜的步骤操作也一定可以实现该功能的。
Emlog网站信息统计的好处
1、网站信息一目了然，不仅能让用户快速的知道其信息，对我们自身运营网站的站长也是提供了极大的便利；
2、利于数据分析，比如用户增长的情况、留言情况等。
Emlog如何实现网站信息统计
冬镜在这里分享2个方法，具体使用那个方法，站长你自己决定。
方法一：利用Emlog官方提供的缓存统计代码，在你需要显示的位置插入以下代码即可。
<?php $sta_cache = Cache::getInstance()->readCache('sta'); ?>
<li>日志数量：<?php echo $sta_cache['lognum']; ?></li>
<li>评论数量：<?php echo $sta_cache['comnum']; ?></li>
<li>微语数量：<?php echo $sta_cache['tbnum']; ?></li>
<li>运行时间：<?php echo floor((time()-strtotime("2018-04-04"))/86400); ?>天</li>
优点：网页加载速度是比较快的；
缺点：很多时候网站信息得不到及时的更新。

方法二：SQL语句查询返回数据
2.1 首先在模板文件 module.php 文件最后添加如下代码
<?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 . "blog WHERE top = 'y' or sortop = 'y' AND type = 'blog'");
return $data['total'];
}
//隐藏文章数
function count_log_hide(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "blog WHERE hide = 'y' AND type = 'blog'");
return $data['total'];
}
//未审核文章数
function count_log_check(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "blog WHERE checked = 'n' AND type = 'blog'");
return $data['total'];
}
//加密文章数
function count_log_pass(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "blog WHERE password !='' AND type = 'blog'");
return $data['total'];
}
//统计页面总数
function count_page_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "blog WHERE type = 'page'");
return $data['total'];
}
//统计评论总数
function count_com_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "comment");
return $data['total'];
}
//统计友链总数
function count_link_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "link");
return $data['total'];
}
//统计微语评论总数
function count_treply_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "reply");
return $data['total'];
}
//统计分类总数
function count_sort_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "sort");
return $data['total'];
}
//统计子分类数
function count_sort_mod(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "sort WHERE pid != 0");
return $data['total'];
}
//统计标签总数
function count_tag_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "tag");
return $data['total'];
}
//统计微语总数
function count_tw_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "twitter");
return $data['total'];
}
//统计用户总数
function count_user_all(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "user");
return $data['total'];
}
//统计管理员总数
function count_user_admin(){
$db = MySql::getInstance();
$data = $db->once_fetch_array("SELECT COUNT(*) AS total FROM " . DB_PREFIX . "user WHERE role = 'admin'");
return $data['total'];
}
//统计作者总数
function count_user_writer(){
$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;
};
?>
2.2 在需要显示的位置插入如下调用变量即可。
<ul> <li>文章总数：<?php echo count_log_all();?></li> <li>置顶文章：<?php echo count_log_top();?></li> <li>隐藏文章：<?php echo count_log_hide();?></li> <li>待审文章：<?php echo count_log_check();?></li> <li>加密文章：<?php echo count_log_pass();?></li> <li>页面总数：<?php echo count_page_all();?></li> <li>评论总数：<?php echo count_com_all();?></li> <li>友链总数：<?php echo count_link_all();?></li> <li>微语评论：<?php echo count_treply_all();?></li> <li>分类总数：<?php echo count_sort_all();?></li> <li>子分类数：<?php echo count_sort_mod();?></li> <li>标签总数：<?php echo count_tag_all();?></li> <li>微语总数：<?php echo count_tw_all();?></li> <li>用户总数：<?php echo count_user_all();?></li> <li>管理员数：<?php echo count_user_admin();?></li> <li>作者总数：<?php echo count_user_writer();?></li> <li>附件总数：<?php echo count_att_all();?></li> <li>最后更新：<?php echo last_post_log();?></li> </ul>
具体的CSS样式冬镜就不给大家提供了，比较每个人喜欢的不一样，而且最好和自己的网站模板主题搭配才是最佳的。
优点：动态查询，所以数据可以说是实时更新，不会担心有数据更新不及时。
缺点：网页打开速度慢（相比方法一速度是毕竟慢的）。
