I stumbled onto using Netbeans for PHP a few months ago while doing some Java work. I use it almost exclusively for PHP now (I also use geany for quick edits).

I stumbled onto using Netbeans for PHP a few months ago while doing some Java work. I use it almost exclusively for PHP now (I also use geany for quick edits). While it's not quite as slick as the Java support, it is a world better than anything else I've used. Also the subversion and mercurial integration kicks ass. Hope oracle continues to support development, but if not, we have the source.
