Question

Upon transfering my site from one server to another, some functions started behaving differently.

The problem lies in building my rss feed. My feed are composed of database posts containing html, and to show them correctly in the feed I then need to change the picture paths to full domain paths, instead of just server root. For this purpose I use simple html dom (http://simplehtmldom.sourceforge.net).

When outputting the varaible html in Content-type: appilication/rss+xml it will show “Object id #1”. Should I choose to output it before setting content-type, I get the right html. (in this case < p >test< /p >)

How come I can’t output the variable html inside content-type rss+xml?

require_once($_SERVER['DOCUMENT_ROOT'].'/lib/config.php');
require_once($_SERVER['DOCUMENT_ROOT'].'/lib/functions/simple_html_dom.php');

$html = str_get_html("<p>test</p>");

foreach($html->find('img') as $e) {
    $e->src = $siteconfig['full_domain'].$e->src;       
}

header("Content-Type: application/rss+xml; charset=UTF-8");

$rssfeed = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
$rssfeed .= "<rss version=\"2.0\">\n";
$rssfeed .= "<channel>\n";
$rssfeed .= "<title>Headline</title>\n";
$rssfeed .= "<language>da</language>\n";
$rssfeed .= "<item>\n\t";
$rssfeed .= "<description><![CDATA[".$html."]]></description>\n\t";
$rssfeed .= "</item>\n";
$rssfeed .= "</channel>\n";
$rssfeed .= "</rss>";

echo $rssfeed;

try this:

$rssfeed .= "<description><![CDATA[".$html->save()."]]></description>\n\t";
