Using RDi for PHP source

I am trying to use Rdi to edit PHP source.

My first problem is if I drill down on the IFS and double click a .php
file it opens with Adobe Dream Weaver - As this is the program default for
the name .php

I can change the default program but what do I set it to ? Or if I add a
new parser option in Rdi Windows ==> Preferences for document type PHP
what would I set the document parser to ?

I can of course right click on the file and select text editor.

If I was to create a new project specific for the PHP project what project
type would you suggest I select and any other setup options that may be
beneficial to working with PHP ?


Thank you for any suggestions / responses.
