Edit PHP files as HTML

Hello,

I'm considering using PyCharm for both Python and HTML+JavaScript development so I downloaded the full demo.

When dealing with .py, .js, .html... files everything seems perfect, but I want also to edit some HTML files with the PHP extension. I know that you cannot use PyCharm for PHP development, but what I actually want is to edit HTML code. I don't care if it grays out the PHP code inserts, but I want to be able to have all Webstorm functionalities for the HTML code.

Is there a way to do something like "associate PHP files to HTML language"?

Thanks!
