How to display RSS feeds on your WordPress blog

Do you ever wanted to be able to display any rss feed on your WordPress blog? If yes, here’s a simple code that will do the job without using the deprecated wp_rss() function.

The following code have to be pasted wherever you want to display the feed.
Don't forget to update the feed url on line 3. Number of items to be displayed can be defined on line 6.

<?php
include_once(ABSPATH . WPINC . '/rss.php');
$feed = 'http://example.com/feed/';
$rss = fetch_feed($feed);
if (!is_wp_error( $rss ) ) :
    $maxitems = $rss->get_item_quantity(3);
    $rss_items = $rss->get_items(0, $maxitems);
    if ($rss_items):
        echo "<ul>\n";
        foreach ( $rss_items as $item ) : 
            echo '<li>';
            echo '<a href="' . $item->get_permalink() . '">' . $item->get_title() . "</a>\n";
            echo '<p>' . $item->get_description() . "</li>\n";
        endforeach;
        echo "</ul>\n";
    endif;
endif;
?>
