配置网站统计数据

配置方式为PHP代码，如下图：

建站天数： <?php
function diffDate($date1,$date2){
    $datetime1 = new DateTime($date1);
    $datetime2 = new DateTime($date2);
    $interval = $datetime1->diff($datetime2);
    $time['y']         = $interval->format('%y');
    $time['m']         = $interval->format('%m');
    $time['d']         = $interval->format('%d');
    $time['h']         = $interval->format('%H');
    $time['i']         = $interval->format('%i');
    $time['s']         = $interval->format('%s');
    $time['a']         = $interval->format('%a');    // 两个时间相差总天数
    return $time['y'].'年 '.$time['m'].'月 '.$time['d'].'天';
}

echo diffDate(date('Y-m-d H:i:s', time()), '2019-08-16 00:00:00');
?>

文章总数： <?php $count_posts = wp_count_posts(); echo $published_posts = $count_posts->publish;?> 篇

最后更新： <?php
function get_last_post_date(){
    global $wpdb;
    $last_post_date='';
    $last=$wpdb->get_var("select date_format(post_date, '%Y-%m-%d') from $wpdb->posts where post_type='post' and post_status='publish' order by post_date desc limit 1");

    return $last;
}

echo get_last_post_date();
?>

总浏览量： <?php
function get_all_post_view(){
    global $wpdb;
    $count=0;
    $views= $wpdb->get_results("SELECT t1.* FROM $wpdb->postmeta t1,$wpdb->posts t2  WHERE t1.meta_key='views' and t1.post_id=t2.id and t2.post_type='post'");
    foreach($views as $key=>$value){
        $meta_value=$value->meta_value;
        if($meta_value!=' '){
            $count+=(int)$meta_value;
        }
    }

    return $count;
}

echo number_format(get_all_post_view(),0,".",",");
?> 人次

总评论数： <?php $total_comments = get_comment_count(); echo $total_comments['approved'];?> 条

效果：
