I just downloaded the Aptana IDE and then sebsequently installed the php plugin.
One thing I noticed is that for under 30 bucks, you can deploy a php/mysql app to the Aptana cloud! There is a free one month trial, I will check it out.
The cloud supports SVN, state and production servers out of the box, if it works that is a pretty nice turn key solution to for getting apps out there.
I think I get cloud computing now...
