basically below is the 2 sets of coding, im trying to make an rss feed appear on the page, but for each headline i would like to have an image appear :) bullet.gif basically and it to appear for any headline that gets made after that...

any ideas for the coding and where to put it?
muchos appreciated :D

andy =)

[b]On the main index.php:[/b]
[code]<?php
// Include the file that does all the work
include("info/rssreader.php");

// This is the URL to the actual RSS feed. Change this value
// if you want to show a different feed.
$url="http://feeds.feedburner.com/PP";

// Create an instance of the rssFeed object, passing it
// the URL of the feed
$rss=new rssFeed($url);

// If there was an error getting the data
if($rss->error){
// Show the error
print "<h1>Error:</h1>\n<p><strong>$rss->error</strong></p>";
}else{

// Otherwise, we have the data, so we call the parse method
$rss->parse();


// Show the news stories
$rss->showStories();
}
?>[/code]

Last modified: May 2, 2005

June 21, 2005 - Added some minor error handling updates

May 2, 2005 - Modified again to drop using cURL library and
instead use direct socket i/o. This eliminates any external
server configuration dependencies.

Apr 21, 2005 - Modified to use cURL library instead of
file_get_contents function. This class now has a dependency
in that the curl library must be enabled on the server.
