The server had issues, the post was sent twice and I couldn't delete it, so I thought why not ask another question while I'm here? Is there a free php editor for windows that has some capabilities like colors, auto complete...etc?
I can't remember if it has auto complete (last I used it was in terminal), but have you checked out VIM? http://www.vim.org/
