Earlier today, EvilWalrus re-added support for other languages, including Perl and DHTML. Their main focus will still be the PHP world, but they will also try to help in these other areas too.
DevShed.com has posted the second in their PHPShop series. This one starts to get into the meat of the software and how to deal with some of its quirks. And, lastly, Zend.com also has a new tutorial all about making advanced web site stats with PHP. This seems to be a bit more in-depth than the previous, simpler stats tutorial.
