I have been using RubyMine since this past summer for all my Rails development and I can't say enough good things about it. Since then I have always been hoping for a similar IDE from JetBrains for ASP.NET MVC.
Well, that hasn't happened, but JetBrains has a public preview of their Web IDE which is very handy for PHP and Web Development. I can't compare it to anything since I haven't played with it much yet, but it definitely looks promising. It has lots of the things you want from an editor, such as code completion, intellisense, refactoring, version control support, debugging, code navigation, etc.
I have been thinking a lot about learning PHP, so this might be a good IDE to help get started. If you are interested in an intelligent IDE for PHP and Web Development, doesn't hurt to swing by the JetBrains website and download a trial of their Web IDE here.
