您可以使用以下选项：

// prepare arguments
$args  = array(
// search only for Authors role
\'role\' => \'Author\',
// order results by display_name
\'orderby\' => \'display_name\'
);
// Create the WP_User_Query object
$wp_user_query = new WP_User_Query($args);
// Get the results
$authors = $wp_user_query->get_results();
// Check for results
if (!empty($authors))
{
    echo \'<ul>\';
    // loop trough each author
    foreach ($authors as $author)
    {
        // get all the user\'s data
        $author_info = get_userdata($author->ID);
        echo \'<li>\'.$author->ID.\' \'.$author_info->first_name.\' \'.$author_info->last_name.\'</li>\';
    }
    echo \'</ul>\';
} else {
    echo \'No authors found\';
}
