I'm using Aptana. I used to use PHP Eclipse and EasyEclipse PHP, but I've no idea why I stopped using them. I went thought a phase where I like this feature in that IDE, but I like this one in another. Basically, each had their pros and their cons, so I decided to stick with Aptana, as it seems to support more file types, and has more features that are useful to me.
