Here i will show you how to use SimplePie functionality in WordPress templates. I presume that you have the basic understanding of SimplePie and know how to add PHP code to your WordPress template. If you are beginner and don’t have enough knowledge on SimplePie than i recommend to read SimplePie wiki first.
To use SimplePie in WordPress template you need to include ‘feed.php‘ which is present in wp-includes folder. This file contains functions which are used in WordPress to deal with Feeds. The file also contains fetch_feed() function which is used to build SimplePie object RSS and ATOM from URL.
Find the example code snippet below-
<?php
//WORDPRESS modified
include_once(ABSPATH . WPINC . '/feed.php');
// Get a SimplePie feed object from the specified feed source.
$feed = fetch_feed('http://themeappears.com/premiumwordpresstemplates/feed/rss/');
