是 啊

$wpdb2 = new wpdb(\'dbuser\', \'dbpassword\', \'dbname\', \'dbhost\');

// get 10 posts, assuming the other WordPress db table prefix is "wp_"
$query = "SELECT post_title, guid FROM wp_posts
          WHERE post_status = \'publish\'
           AND post_type = \'post\'
          ORDER BY post_date DESC LIMIT 10";

$someposts = $wpdb2->get_results($query, OBJECT);
foreach($someposts as $somepost)
  echo "<a href=\\"{$somepost->guid}\\">{$somepost->post_title}</a><br />";

另一种方法是使用HTTP api:

要在其中显示数据的第一个站点中的代码：

$send = array(
  \'body\' => array(
    \'action\' => \'get_some_posts\',
    // send other data here, maybe a user/password if you\'re querying senstive data
  ),
  \'user-agent\' => \'RodeoRamsey; \'.get_bloginfo(\'url\')
);

$response = wp_remote_post(\'http://yoursiteurl.com/\', $send);
  if (!is_wp_error($response) && ($response[\'response\'][\'code\'] == 200)) echo $response[\'body\'];

在第二个站点的主题函数中编写代码。php（或创建插件）：

add_action(\'template_redirect\', \'process_post_request\');
function process_post_request(){
  if($_POST[\'action\'] == \'get_some_posts\'):
    $posts = new WP_Query();
    $query = array(\'posts_per_page\' => 10);
    $posts->query($query);
    while ($posts->have_posts()):
      $posts->the_post(); // here\'s the usual loop
      ?>

      <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
      <?php the_content(); ?>

      <?php
   endwhile;
   die();
  endif;
}

从“格式化”的角度来看，第二种方法更简单、更灵活。例如，在这里，您可以轻松地将帖子缩略图作为html进行回显，而使用数据库方法，您将很难获得指向缩略图图像的链接。。。
