vim: php syntax highlighting in HAML with :php filter [closed]

Question

I'm using the :php HAML filter that is supplied with haml-contrib to write blocks of php code inside a haml file.

this allows me to write:

!!! 5
%html
     %body
     -# HAML code ...
     :php
         // php code ...

I want to hightlight the php code in vim using this vim-tip. However, the default php syntax file that is supplied with my stock vim only highlights php code that is inside <?php ,?> tags.

How can I get around this?

Note that I can get the vim-tip to work, so highlighting the following:

!!! 5
%html
     %body
     -# HAML code ...
     :php
         <?php
              // php code ...
         ?>

does work! It just creates bad HAML output (double <?php ... ?> tags) and doesn't reflect the simplicity I want to achieve using HAML.

Answer 1

It's more along the lines that you need updated HAML syntax rules that allow vim to detect when you're going from haml->php.

Remember, there's no such thing as a "php script". There's only files which have php code blocks embedded in them, and those code blocks are delimited with <?php ... ?>. There's no way for vim's php rules to directly detect that you've broken into php mode, because you don't have the <?php to signal that.
