Best way to get user id for get_users function?

Question

I'm trying to make a table of users by role type. What is the best-practices method of getting the user id? My goal is to print each users first & last names, username and email.

What I have now:

$get_admins = array(
    'blog_id' => $GLOBALS['blog_id'],
    'role' => 'administrator',
);

$blogusers = get_users($get_admins);
foreach ($blogusers as $user) { 
$userid = get_userdata($bloguser->user_id);
$user_info = get_userdata($userid);

    echo '<tr>';
        echo '<td>'. $user_info->user_firstname .'</td>';
        echo '<td>'. $user_info->last_name .'</td>';
        echo '<td>'. $user->user_login .'</td>';
        echo '<td>'. $user->user_email .'</td>';
    echo '</tr>';
}

note: In my example above getting the user id does not work.

Codex reference: get_users()

Your code doesn't work because you're using $bloguser instead of $user.

And there's no point in calling get_userdata() since get_users() already returns user objects:

foreach ($blogusers as $user) {
    echo '<tr>';
        echo '<td>'. $user->first_name .'</td>';
        echo '<td>'. $user->last_name .'</td>';
        echo '<td>'. $user->user_login .'</td>';
        echo '<td>'. $user->user_email .'</td>';
    echo '</tr>';
}
