Douglas Clifton has taken some time to look at a group of the web application frameworks out there (not just PHP - Pearl, Python and Ruby too) and offer up some opinions on them. This new post is the result.
It just wouldn't be fair after my last post to ignore the tried-and-true server-side Web application frameworks. I am certainly familiar with all of them, though I haven't necessarily used every one in a production environment.
The among the PHP frameworks mentioned are: Drupal, CodeIgniter, CakePHP and Symfony. His personal choice was CodeIgniter:
It's light weight, fast, and stays out of your way. There are any number of class modules to choose from, and you can discard what you don't need to lighten the load even more.
