PW reminds me of brunch, as described by Jacques in The Simpsons - "It’s not quite breakfast, it’s not quite lunch, but it comes with a slice of cantaloupe at the end."
For breakfast, read frameworks like CodeIgniter or CakePHP and for lunch read CMSs like Joomla or Drupal. And the slice of cantaloupe is the "OH. MY. GOD." moments that just keep happening.
