How to get content through bbcode

[Pooligans]

I want to be able to do this:

[bbcode]some_id[/bbcode]

will get the content from http://www.domain.com/script.php?id=some_id

and replace with this

[ code ]content[/ code ]

and parse the code bbcode.


Any help or guide or just a direction will be helpful, even an existing mod that does something similar which i can look at and understand how they did it.

Thanks!
