rss feed trouble

[nick3592]

Hi, i have made a rss feed that automatically updates, what i done use php to grab information from the database as new content is added in xml. Everything seems okay but when i click subscribe to rss feed it displays "Failed to load feed". My extension is .php is there any way that can be a problem? I am a little new in making rss feeds in php so any help is appreciated.
Heres my code.

<?php

include("../scripts/connect_to_mysql.php");

header("Content-Type: application/xml; charset=ISO-8859-1");

echo '<?xml version="1.0" encoding="ISO-8859-1" ?>
<?xml-stylesheet type="text/xsl" ?>
<rss version="2.0">
<channel>
<title>Example - Latest Content</title>
<link>http://example.com</link>
<description>Latest Content On http://example.com</description>';

$query = "SELECT * FROM table ORDER BY dateadded DESC limit 15";
$result = mysql_query($query);

while($row = mysql_fetch_assoc($result))
{
	$name = $row['name'];
	$featured = $row['featured'];
	$description = $row['description'];
	$release = $row['released'];
	$information = $row['information'];
	$dateadded = $row['dateadded'];
	$dateadded = date("r", strtotime($dateadded));

echo '
	<item>
			<id>' . $information . '</id>
			<featured>' . $featured . '</featured>
			<title>' . $name . '</title>
			<description>' . $description . '</description>
			<release>' . $release . '</release>
			<link>http://example.com/category/information?information=' . $information . '</link>
			<enclosure url="http://example.com/category/information?information=' . $information . '"/> 
			<pubDate>' . $dateadded . '</pubDate>
	</item>
';
}
echo "</channel>
</rss>";
