效果

Content.php添加

1. 将以下代码加到/usr/themes/handsome/libs/Content.php中，放在class Content的上面

/*访问总量*/
function theAllViews(){
         $db = Typecho_Db::get();
         $row = $db->fetchAll('SELECT SUM(VIEWS) FROM `typecho_contents`');
             echo number_format($row[0]['SUM(VIEWS)']);
 }

/*响应时间*/
function timer_start() {
    global $timestart;
    $mtime = explode( ' ', microtime()  );
    $timestart = $mtime[1] + $mtime[0];
    return true; 
}
timer_start();
function timer_stop( $display = 0, $precision = 3  ) {
    global $timestart, $timeend;
    $mtime = explode( ' ', microtime()  );
    $timeend = $mtime[1] + $mtime[0];
    $timetotal = number_format( $timeend - $timestart, $precision  );
    $r = $timetotal < 1 ? $timetotal * 1000 . " ms" : $timetotal . " s";
    if ( $display  ) {
        echo $r;
    }
    return $r;
}

/*全站字数*/
function allOfCharacters() {
    $chars = 0;
    $db = Typecho_Db::get();
    $select = $db ->select('text')->from('table.contents');
    $rows = $db->fetchAll($select);
    foreach ($rows as $row) { $chars += mb_strlen(trim($row['text']), 'UTF-8'); }
    $unit = '';
    if($chars >= 10000)     { $chars /= 10000; $unit = '万'; } 
    else if($chars >= 1000) { $chars /= 1000;  $unit = '千'; }
    $out = sprintf('%.2lf %s',$chars, $unit);
    return $out;
} 

/*在线人数*/
function online_users() {
    $filename='online.txt'; //数据文件
    $cookiename='Nanlon_OnLineCount'; //Cookie名称
    $onlinetime=30; //在线有效时间
    $online=file($filename); 
    $nowtime=$_SERVER['REQUEST_TIME']; 
    $nowonline=array(); 
    foreach($online as $line){ 
        $row=explode('|',$line); 
        $sesstime=trim($row[1]); 
        if(($nowtime - $sesstime)<=$onlinetime){
            $nowonline[$row[0]]=$sesstime;
        } 
    } 
    if(isset($_COOKIE[$cookiename])){
        $uid=$_COOKIE[$cookiename]; 
    }else{
        $vid=0;
        do{
            $vid++; 
            $uid='U'.$vid; 
        }while(array_key_exists($uid,$nowonline)); 
        setcookie($cookiename,$uid); 
    } 
    $nowonline[$uid]=$nowtime;
    $total_online=count($nowonline); 
    if($fp=@fopen($filename,'w')){ 
        if(flock($fp,LOCK_EX)){ 
            rewind($fp); 
            foreach($nowonline as $fuid=>$ftime){ 
                $fline=$fuid.'|'.$ftime."\n"; 
                @fputs($fp,$fline); 
            } 
            flock($fp,LOCK_UN); 
            fclose($fp); 
        } 
    } 
    echo "$total_online"; 
}

sidebar.php添加

2. 找到/usr/themes/handsome/component/sidebar.php文件，找到合适位置添加代码

我放的位置是

      <!--博客信息-->
         <?php if (@!in_array('info', Utils::checkArray($this->options->sidebarSetting))): ?>
      <section id="blog_info" class="widget widget_categories wrapper-md clear">
       <h5 class="widget-title m-t-none text-md"><?php _me("博客信息") ?></h5>

下方添加如下代码：

 <!--自定义统计-->
 <li class="list-group-item text-second">
   <span class="blog-info-icons">
     <i data-feather="edit-3">
     </I>
   </span>
     <span class="badge pull-right">
       <?php echo allOfCharacters(); ?>
   </span>
     <?php _me("全站字数") ?>
 </li>

 <li class="list-group-item text-second">
   <span class="blog-info-icons">
     <i data-feather="users">
     </i>
   </span>

   <span class="badge pull-right">
     <?php echo theAllViews(); ?>
   </span>
     <?php _me("访客总数") ?>
 </li>

 <li class="list-group-item">
   <i class="glyphicon glyphicon-user text-muted text-muted">
   </i>
     <span class="badge pull-right">
       <?php echo online_users() ?>
     </span>
      <?php _me("在线人数") ?>
 </li>

 <li class="list-group-item text-second">
    <span class="blog-info-icons">
      <i data-feather="refresh-ccw">
        </i>
    </span>
    <span class="badge pull-right">
      <?php echo timer_stop(); ?>
      </span>
        <?php _me("响应耗时") ?>
 </li>
