I'm hooked on Eclipse with phpEclipse, pyDev, and Subclipse (SVN). Probably relatively heavy-weight compared to Notepad++ but its got team perspective and source control stuff which is super useful/necessary.

What'd you use before Notepad++?

I was using Dreamweaver (version 8?). It's inbuilt FTP client is really slow. I did like its syntax highlighting though, better than Notepad++.

Ah fair enough. I just have Samba setup with the web directories mounted as a network share. Mostly working with Python, so I've symlinked important bits in site-packages across to the shared directory in the user's home folder. It works really well, even with my hideously underpowered Via EPIA box. Still using FreeBSD btw, loving it.

If you ever need source control give Eclipse a whirl, I find it's lighter weight than Dreamweaver is, and of course you can run it on your Mac too.
