How to reference a phrase

[tscargo]

In a template that I use in my own script I am trying to make use of some phrases, e.g.:

{vb:rawphrase post_comment}

Somehow the phrase is not 'replaced'. Is there something I need to reference in my php script before I can use phrases ?

Thanks,

Taco

I am amazed that my question has not been answered, as it seems to be a quite simple question (and probably answer)

With the help of the lead-programmer of VaultWiki I have figured it out. I needed to use the function fetch_phrase_group from includes/functions_databuild.php.
