How to determine if theres a next page

I am new to wordpress development, just trying to convert my HTML into a WordPress theme, I started with Chris Coyer’s blank theme.

<div class="navigation">
    <div class="next-posts">
        <?php next_posts_link('&laquo; Older Entries') ?>
    </div>
    <div class="prev-posts">
        <?php previous_posts_link('Newer Entries &raquo;') ?>
    </div>
</div>

How can I output the div only if there is a next_posts_link(). I need this as I will be using <ul> for my pagination. If I don’t do that, I will get an empty bullet

You can use get_previous_posts_link and get_next_posts_link
to determine if they exists like this:

$prev_link = get_previous_posts_link(__('« Older Entries'));
$next_link = get_next_posts_link(__('Newer Entries »'));
// as suggested in comments
if ($prev_link || $next_link) {
  echo '<ul class="navigation">';
  if ($prev_link){
    echo '<li>'.$prev_link .'</li>';
  }
  if ($next_link){
    echo '<li>'.$next_link .'</li>';
  }
  echo '</ul>';
}

Hope This Helps
