Jeff Rubinoff from Sun has passed along a link to a developer blog they're hosting covering the development of their NetBeans for PHP project's latest advancements.

We at Sun have been working on a PHP editor in NetBeans IDE. The first full-featured version will go out in our 6.5 release, scheduled for November, but it's available for use already in our daily builds. [...] We're not PHP developers, strictly speaking, we're developing a tool for PHP developers. However, we are trying to get as much feedback from PHP developers as possible.

The blog already has tons of content - tutorials, software updates, screencasts, personal experiences - all covering the development of the next version (beta download) of the PHP tools in NetBeans.
