Looking for online PHP editors

Editing the web from the web

[StuffOfInterest]

I've seen lots of posts regarding PHP development environments, and I already have some good ones to use offline. Still, there has been many times when I'm away from home and need to get in and edit a file.

Has anyone run across a good web based editor for PHP? Ideally, the editor would allow for updating a file and checking it's syntax using the built-in PHP functions for syntax checking and color highlighting. Once the result is accepted, the edited file could then replace the original.

Pushed further out, it is easy to imagine an online editor with versioning ability to allow rollback to an earlier saved version. Another nice feature would be working on the code on one website and then either copying or uploading it to another site. All should be possible, and straight forward, but I'm not sure if anyone has put the pieces together in an open source project.

Any ideas?

Thanks.

I haven't seen anything like that, but could you use emacs via the shell? Or are you looking for something that works when you literally have nothing but browser access via the web (i.e. internet cafe situation, rather than travelling with your laptop situation)?

Ergophobe, very much the latter. Being that I do my primary site work (and testing) under Linux, it isn't always easy to transport the environment around. Being able to edit directly on a website has some definite advantages for portability and quick updates.
