PHP s3 Objects

I have looked through a few php5 objects that will do all the s3 stuff for me and the best one I have found so far is http://code.google.com/p/php-aws/source/browse/trunk/class.s3.php# I have yet to actually use it so we will see how that goes. It seems like it works pretty well. Don't forget to install php5-curl (that is what it is on ubuntu anyway) because it uses that.
