WACT, good enough to learn PHP for?
I was pointed to WACT today, the Web Application Component Toolkit for PHP. It takes a more disciplined approach to development than I'm accustomed to seeing in the PHP world. It looks very interesting. If I ever need to do something in PHP, I'd rather use something like WACT than hacking plain, fugly, terrifyingly unstructured PHP.
I'll add it to my to-investigate list.
