[Noskiw]

function topic($input){ 
//bbcode 
return nl2br(strip_tags(stripslashes(htmlspecialchars($input)))); 
}

 

there is my function where my bbcode code should go, but i wouldn't know how to do it.

There are probably a zillion (over-exaggerated a little) tutorials out there that will cover the basics of a BB Code system. Try this one for starters.
