Creating an advanced BBCode

[ralle89]

have you ever seen the [highlight] mod for vbulletin? well I don't understand the source of it, but I am making something similiar to that.
I don't know which hook to use when wanting to modulate the text..

I have seem something in the source saying
[php] //

PHP Code:

            $tag_list['no_option']['php'] = array(
                'callback' => 'handle_bbcode_php',
                'strip_empty' => true,
                'stop_parse' => true,
                'disable_smilies' => true,
                'disable_wordwrap' => true,
                'strip_space_after' => 1
            ); 


SO I would like to make something similiar to that.. But I dunno what to set these values to. if we said my function was called highlight_kralimut().

And I want to do this with hooks and plugins
