如何在Wordpress中获取循环外的所有现有标记

$posts = get_posts();
foreach ($posts as $post) {
    // 处理和显示标记
    echo $post->post_title;
}

$query = new WP_Query(array(
    'post_type' => 'post',
    'posts_per_page' => -1
));
if ($query->have_posts()) {
    while ($query->have_posts()) {
        $query->the_post();
        // 处理和显示标记
        the_title();
    }
}
wp_reset_postdata();

global $wpdb;
$posts = $wpdb->get_results("SELECT * FROM $wpdb->posts WHERE post_type = 'post'");
foreach ($posts as $post) {
    // 处理和显示标记
    echo $post->post_title;
}
