Essential Tools for a PHP Developer

Tobias Schlitt has just posted some slides from his talk entitled "6 essential PHP development tools in 60 minutes". I flicked the 90 or so slides in PDF format, they pretty much mirror my development environment.

Tobias left out 2 must haves from my personal list. Vim, the only editor I can use for any prolonged period of hacking (go easy emacs fanbois). Although not really a PHP tool, Firebug, is an essential tool for any serious modern web application developer,

With this environment hacking on PHP based web apps should be a breeze.

As a side note I am starting to play with git after watching Linus' Google Tech Talk on it, and I am starting to like a it, so maybe soon it will be s/svn/git for me.
