Code:

public static function bbcode($str) {
	// Optionally, do this to break up words longer than 20 characters (without breaking code)
	// $str = preg_replace("/(([^\(\)\{\}\[\]_]\S){20})/","$1 ",$str);
	// Make sure htmlentities has been run through the text and that
	// $str = preg_replace("/(\r|\n)/","<br />",$str); // has been run through

This is a neat little function I made for my php A3 framework. Get rid of "public static" if you want to use this as a function. Normally it's inside my framework class.

Oh, and none of this is copied from anywhere. I designed this 2-days ago on my own. So taking it without credit, is strictly forbidden since my framework costs money.

------------------------------

As a test, I wrote this.

Framework Version
<?php
require("framework/a3.framework.php");
$str = ":smile::smile:BOLD[b]BOLD[/b] Hello [i][b]Hello[/b][/i]";
echo a3::bbcode($str);
?>

This version
<?php
// Put code above here right here (of course without "public static")
$str = ":smile::smile:BOLD[b]BOLD[/b] Hello [i][b]Hello[/b][/i]";
echo bbcode($str);
?>

I like posting code crap here. Eat it up! Rate it. Byte me.

Only problem I see, is stacking noparse will break noparse.

Edit:

Oh, I just found out that it also breaks Jelsoft's bb code system. How wonderful, I win! That means that apparently no one else has really come up with any other means of pulling that off. The way I did it is probably fairly similar to this boards way of doing it.

Outcome
:smile::smile:BOLD[b]BOLD[/b] Hello [i][b]Hello[/b][/i]
