Initial vanilla php example

* Bam! It's been more than seven or eight years since I did some
  PHP programming, but it's striking how fast it lets itself be
  molded. Current implementation is already feature rich, after
  only a couple of hours. Say what you want, but PHP is a damn
  pragmatic tool.
Renamed example
Feature complete PHP Vanilla example

* A bit rough aroung the edges perhaps, but functional. All the
  features are there.
