LastRSS CakePHP Component
LastRSS is a PHP class for retrieval and parsing of RSS feeds. This is a wrapper to that class making it easy to use in the CakePHP framwork. Much of this component is taken from the work of Matt Curry (http://bakery.cakephp.org/articles/view/simplepie-cakephp-component) and Scott Sansoni (http://cakeforge.org/snippet/detail.php?type=snippet&id=53).
Download
You can download the required LastRSS files at http://lastrss.oslab.net/Usage
- CakePHP either 1.1 - I have not tested on 1.2
- Download LastRSS (http://lastrss.oslab.net/) and unzip the contents into the vendors folder and rename the file to 'lastrss.php' (all lowercase).
- Download the component (or paste the full code from below) and put it in 'app/controllers/components/lastrss.php'.
- Include the component in any controller that will need it.

3 Cannot Redeclare lastrssComponent
Line 242 in lastrss.php is the final line of the class. So it's after the file has been included by the component. I tried renaming classes, etc. and then LastRSS cannot instantiate.
I'm sure it's something small I'm overlooking. Any thoughts?
