What is wrong with this code

Im using this code to publish a feed of our blog's RSS but its not working and I can't figure out why.

It used to work until a month or so ago (i just realized its not working anymore). I'm thinking it could be because a higher version of php doesn't recognize one of the commands - but i'm not sure. hence why im asking for your help

        $url= $this->get_template_vars('myurl');

        $feed = file_get_contents($url);

        if ($feed <> false) {
            $rss = new SimpleXmlElement($feed);   
            $i = 0;   
            foreach($rss->channel->item as $entry) {
                if ($i >=3) {
                    break;
                } else {
                    echo "<div class='HomepageArticlesWrapper'><p><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a></p>";
                    echo "<p>" . $entry->description . "</p></div>"; 
                    $i += 1;    
                }
            }
        }

Do you have error reporting turned on? I tested your code with a feed and it worked.

 

I dont have error reporting turned on.

Im using this in a Smarty file so this is the entire code:

        {assign var="myurl" value=$smarty.const.SITE_RSS}
    {php}

        $url= $this->get_template_vars('myurl');

        $feed = file_get_contents($url);

        if ($feed <> false) {
            $rss = new SimpleXmlElement($feed);   
            $i = 0;   
            foreach($rss->channel->item as $entry) {
                if ($i >=3) {
                    break;
                } else {
                    echo "<div class='HomepageArticlesWrapper'><p><a href='$entry->link' title='$entry->title'>" . $entry->title . "</a></p>";
                    echo "<p>" . $entry->description . "</p></div>"; 
                    $i += 1;    
                }
            }
        }


    {/php}

I recommend turning on error_reporting and see what error it shows you.

 

This is what i get

Warning: file_get_contents() [function.file-get-contents]: http:// wrapper is disabled in the server configuration by allow_url_fopen=0 in/usr/home/path... on line 39

Warning: file_get_contents(http://feeds.feedburner.com/Feed) [function.file-get-contents]: failed to open stream: no suitable wrapper could be found in/usr/home/path... on line 39

Your hosting provider/server administrator will need to enable allow_url_fopen.
