PHP RSS Feed not showing

New to PHP and was just playing around with RSS feeds. I'm currently just trying to display the RSS feed from here: http://ift.tt/RwfqMp, but I think my code is broken somewhere and was hoping someone could shed some light on the issue.

This is the function I am using:

<?php

function fetch_news(){
    $data = file_get_contents('http://ift.tt/RwfqMp');
    $data = simplexml_load_string($data);

    $articles = array();

    foreach ($data->channel->item as $item){
        $articles[] = array(
            'title'     => (string)$item->title,
            'content'   => (string)$item->content,
            'href'      => (string)$item->href,
            'published' => (string)$item->published,
            );
    }

    print_r($articles);
}

?>

When loading the page no content is displaying :( All I get is this:

      Array ( )

Any Ideas on what I am doing wrong? I'm guessing it has something to do with that foreach statement.

Thanks for any help :)
