This popped up in my aggregator thanks to PlanetPHP. My development environment is similar to the one Sean uses, I use Eclipse (3.1RC) with PHPEclipse, TortoiseSVN because the silly SVN client doesn’t work that well in Eclipse, Vim and jedit as my secondary editors and Putty for SSH. I do most of my development against MSSql so I use Query Analyzer and Service Manager, I do however have Apache and MySQL installed. I don’t think I really have anything special happening though.
I wish I could use Zend Studio it’s just really hard for me to get used to and I end up going back to what I know.
