Merge multiple RSS feeds with SimplePie
<?php | |
/* Merge multiple RSS feeds with SimplePie | |
* | |
* Just modify the path to SimplePie and | |
* modify the $feeds array with the feeds you want | |
* | |
* You should probably also change the channel title, link and description, | |
* plus I added a CC license you may not want | |
* | |
* Help from: http://www.webmaster-source.com/2007/08/06/merging-rss-feeds-with-simplepie/ | |

On line 16, if you are running a more recent version of simplepie, just change this:
include_once('/path/to/simplepie/simplepie.inc'); // Include SimplePie
to this:
include_once('./php/autoloader.php');
(my autoloader.php file is in ./php/, if yours is in a different place, just change the path)
EDITED:
For people who doesn't know how to make this work with SimplePie I created a tutorial step by step from the beginning:
