Web-based equivalent of OpenOffice.org Base or Microsoft Access?

Question

I've currently been using Base/MS Access to create forms etc. that interface with a backend database, to save me writing a backend in PHP. Downside is that it only runs on the desktop. Is anyone aware of any web-based equivalent?

Edit: Should have done more research, I need it to interact with MySQL, not an Access DB.
