Dreamweaver (Score 1)

If you are under Win, Dreamweaver from Macromedia can do great things; but I think, color-highlighting is only for the html mode. It has a ftp client too. Nevertheless I tried it with asp and I'm not sure that it will be as great with php. But you could search in this way. Under Linux, Vim can do Color-highlighting for php, but I thought Emacs did it well too.
