如何将wp查询中的帖子按3分组，同时将每个帖子分别放在各自的div中？

$args = array(
    'posts_per_page' => -1, // 获取所有帖子
    'orderby' => 'date', // 按照日期排序
    'order' => 'DESC', // 降序排序
);

$query = new WP_Query($args);

if ($query->have_posts()) {
    $posts = $query->posts;

    $grouped_posts = array();
    foreach ($posts as $post) {
        $group = floor(($post->ID - 1) / 3) + 1; // 根据ID将帖子分组，每组3个帖子
        $grouped_posts[$group][] = $post;
    }

    foreach ($grouped_posts as $group => $posts) {
        echo '<div class="group">';
        foreach ($posts as $post) {
            // 在这里输出帖子的内容
            echo '<div class="post">';
            echo '<h2>' . get_the_title($post->ID) . '</h2>';
            echo '<div>' . get_the_content($post->ID) . '</div>';
            echo '</div>';
        }
        echo '</div>';
    }
}
