Display Other website's RSS Feed on Your WordPress (Multiple Sources)
===

I have a code to fetch RSS feed from one website and then display it on my WordPress website.
The script is working fine if I have to fetch the RSS from only one website but what I actually looking for is a script which can fetch the RSS from multiple websites say 3 or 4 and display them in one place as a bundle on my WordPress site.

Here is the code I am using:

    <?php include_once(ABSPATH.WPINC.'/feed.php');
    $rss = fetch_feed('http://www.nnedv.org/index.php?format=feed&type=rss');
    $maxitems = $rss->get_item_quantity(10);
    $rss_items = $rss->get_items(0, $maxitems);
    ?>
    <div class="textwidget">
      <div id="dv-news-feed-box">
        <ul id="dv-news-feed">
          <?php if ($maxitems == 0) echo '<li>No items.</li>';
    else
    // Loop through each feed item and display each item as a hyperlink.
    foreach ( $rss_items as $item ) : ?>
          <li> <a target="_blank" href='<?php echo $item->get_permalink(); ?>'
    title='<?php echo 'Posted '.$item->get_date('j F Y | g:i a'); ?>'> <?php echo $item->get_title(); ?></a> </li>
          <?php endforeach; ?>
        </ul>
      </div>
    </div>

Thanks in advance.
