有时做一些统计数据，需要调取WordPress的文章总数、评论总数以及用户总数，这些该如何获取？
以下是常用的代码：
日志总数：<?php $count_posts = wp_count_posts(); echo $published_posts = $count_posts->publish;?>篇
评论总数：<?php echo $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->comments");?>条
分类总数：<?php echo $count_categories = wp_count_terms('category'); ?>个
标签总数：<?php echo $count_tags = wp_count_terms('post_tag'); ?>个
友情链接：<?php $link = $wpdb->get_var("SELECT COUNT(*) FROM $wpdb->links WHERE link_visible = 'Y'"); echo $link; ?>个
网站运行：<?php echo floor((time()-strtotime("2011-7-27"))/86400); ?>天
最后更新：<?php $last = $wpdb->get_results("SELECT MAX(post_modified) AS MAX_m FROM $wpdb->posts WHERE (post_type = 'post' OR post_type = 'page') AND (post_status = 'publish' OR post_status = 'private')");$last = date('Y年n月j日', strtotime($last[0]->MAX_m));echo $last; ?>
