State of formatting php with html?

[1MikeMakuch]

I was just looking for the current status regarding:

... Formatting of files that contain mixed PHP and HTML is still considered unstable - please 
see open issues with the tag inline for details.

If you want to use the plugin in production, we recommend limiting its scope to pure PHP files.

It looks like some progress has been made but wondering how far a long it is/isn't?

Thanks Mike
