I kind of know how to parse bbcode.
But what about implementing it.

Never mind. I figured it out. When i create the bbcode. I want to make it a function. And also use some javascript for the buttons for the forum. Then put the text into the function before putting it into the database!

Now i'm just a little sketchy on the JavaScript part with the buttons =/

Edit: Also sorry to ask, Creating a php synthax highlighter?
