David Van Couvering has posted about some of his experience with the latest version of the NetBeans editor for some of his PHP and Javascript development work.
Yesterday I spent the whole day trying to help a friend in need who had waded in too deep with a contract he has. He has no database experience, and was trying to customize a Wordpress plugin that uses PHP, JavaScript and MySQL. So I downloaded the daily build of the PHP bundle of NetBeans for 6.5 and started working.
He happily notes that things like syntax highlighting, inline documentation and completion were still there in the PHP bundle as well. He also mentions a few other things that could come in handy for the IDE - ssh tunnel support (see here), an "Add Column Wizard" and a "Insert DLL Wizard".
