WYSIWYG development environment for PHP

I'm trying to encourage a client to move from Microsoft to Open standards for web deployment. One of the big advantages claimed for Microsoft is that products like FrontPage make it very easy for people to start writing HTML, and then progress to writing programs in Microsoft server-side languages. I don't want to get into religious wars here about WYSIWYG editing vs editing raw HTML. To win this argument, I need to be able to demonstrate a WYSIWYG editor that runs under Windows, and makes it easy to deploy against (say) Apache, and give a smooth transition through to PHP coding. Any advice please? -- John McCreesh mail: john.mccreesh(a)openlink.org
