RSS FEED from derekallard.com Problem at server

[eluser]Asinox[/eluser]
Hi, i tried the RSS Feed of Derekallard.com, and in my local machine the feed is fine, but in my server i got the error:

Code:

A PHP Error was encountered
Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/nxmedia/public_html/raptitud/system/application/controllers/feed.php:23)

Filename: libraries/Session.php

Line Number: 662

A PHP Error was encountered
Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /home/nxmedia/public_html/raptitud/system/application/controllers/feed.php:23)

Filename: controllers/feed.php

Line Number: 19

Now the controller Feed:

Code:

if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Feed extends Controller{

    function Feed(){
        parent::Controller();
    }
    
    function index(){
        $data['encoding'] = 'utf-8';
        $data['feed_name'] = 'raptitud.com';
        $data['feed_url'] = 'http://www.raptitud.com';
        $data['page_description'] = 'Hip Hop Global desde la Republica Dominicana';
        $data['page_language'] = 'es-ES';
        $data['creator_email'] = 'webmaster [arroba] raptitud [punto] com';
        $data['posts'] = $this->modarticulos->getRecentPosts();    
        header("Content-Type: application/rss+xml"); //HERE IS THE LINE 19
        $this->load->view('feed/rss', $data);
    }
}

Somebody know why?

Thanks for see.

That's usually a sign that you have a space before an opening PHP tab, or after a closing one. Also, be sure you're not echoing something.

I assume you're code has PHP tags (as I don't see any above). If so, you can omit the closing PHP tag completely.

[eluser]Asinox[/eluser]
yes, that was true... space before

Code:

if ( ! defined('BASEPATH')) exit('No direct script access allowed');

Thanks

Where is the problem

[eluser]TheFuzzy0ne[/eluser]
Try adding a space before the closing tag:

Code:

<?php
echo '<?xml version="1.0" encoding="utf-8" ?>' . "\n";
?>

Thanks, but is not working, the same thing

[eluser]Asinox[/eluser]
fixed:

Code:

echo '<?xml version="1.0" encoding="utf-8" '. "?" .'>' . "\n";

[eluser]Asinox[/eluser]
now i have another problem with this line

Code:

<pubDate>&lt;?php echo date('r', $entry->date);?&gt;</pubDate>

error

Code:

<pubDate><div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  A non well formed numeric value encountered</p>
<p>Filename: libraries/Loader.php(673) : eval()'d code</p>
<p>Line Number: 34</p>

</div>1969-12-31T20:33:29-04:00</pubDate>

Why use "r"???? the date field in my table is like 2009-03-10 12:10:04, why the error?, the "r" is optional?

thanks

You can use the predefined DATE_RSS or DATE_ATOM constants instead of 'r' in your view:

Code:

<pubDate>&lt;?php echo date(DATE_RSS, $entry->date);?&gt;</pubDate>

(From the PHP Manual)

Thanks attos but the same error again

Code:

<pubDate><div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">
