当我想显示一篇文章的评论数量时，我在循环中，建议使用哪个函数？

get_post_field( \'comment_count\', get_the_ID() )

或

get_comments_number()  

这是get_post_field 功能：

/**
 * Retrieve data from a post field based on Post ID.
 *
 * Examples of the post field will be, \'post_type\', \'post_status\', \'post_content\',
 * etc and based off of the post object property or key names.
 *
 * The context values are based off of the taxonomy filter functions and
 * supported values are found within those functions.
 *
 * @since 2.3.0
 *
 * @see sanitize_post_field()
 *
 * @param string      $field   Post field name.
 * @param int|WP_Post $post    Post ID or post object.
 * @param string      $context Optional. How to filter the field. Accepts \'raw\', \'edit\', \'db\',
 *                             or \'display\'. Default \'display\'.
 * @return string The value of the post field on success, empty string on failure.
 */
function get_post_field( $field, $post, $context = \'display\' ) {
    $post = get_post( $post );

    if ( !$post )
        return \'\';

    if ( !isset($post->$field) )
        return \'\';

    return sanitize_post_field($field, $post->$field, $post->ID, $context);
}

还有这个idget_comments_number:

 /**
 * Retrieve the amount of comments a post has.
 *
 * @since 1.5.0
 *
 * @param int|WP_Post $post_id Optional. Post ID or WP_Post object. Default is global $post.
 * @return int The number of comments a post has.
 */
function get_comments_number( $post_id = 0 ) {
    $post = get_post( $post_id );

    if ( ! $post ) {
        $count = 0;
    } else {
        $count = $post->comment_count;
        $post_id = $post->ID;
    }

    /**
     * Filter the returned comment count for a post.
     *
     * @since 1.5.0
     *
     * @param int $count   Number of comments a post has.
     * @param int $post_id Post ID.
     */
    return apply_filters( \'get_comments_number\', $count, $post_id );
}

我可以看出他们有不同之处，但我不知道哪一个更好（如果有的话。也许他们都可以）。
