Editing with Coda

I use coda as my text editor/subversion client at the studio I work at. We have many clients who hire us for a redesign of existing websites, meaning we have to stick with their existing file extensions. While I don't have to have an auto complete or color-coder for my PHP (and I write the majority of my code in separate files that are just included in the .开发者_如何学JAVAhtml) It would be nice to be able to use it in .html files.

Is there any way to switch between how Coda interprets the file I am looking at, so that I can use auto-complete and the other features for PHP in an HTML file, or is there a plugin that can accomplish this?

You should be able to add a "custom syntax mode" in the Coda preferences to edit files with the "html" extension using "PHP-HTML" syntax highlighting.
