I'm going to be starting a new PHP project later this week, and as I don't like to reinvent the wheel, I've been looking around for some decent PHP starter applications, i.e., PHP skeleton applications.
As I've looked around for PHP starter projects, this starter application from Grover Ponders looks the best. It seems well-organized, and you can just download a tar.gz file and get to work.
This ZFKit project on GitHub also looks good, and I may give it a shot as well. FWIW, if you want to grab a copy of this PHP starter application, the correct Git command is:
git clone http://github.com/mgkimsal/zfkit.git
Finally, there is this Kenai project as well, though I haven't taken the time to look at it. (Sorry, I haven't used SVN in forever, and can't remember the right SVN command to get a copy of this project.)
It's funny, I can see why these last two projects want to be in a Git or SVN repository, but it's much more user-friendly to provide a tar/gz file. I know I'm being lazy, but it's true.
