Maverfax told me to make one, so I did.

PHP Code:

function bbcode($text) {
    
    $text = strip_tags($text, '<br />');
    
    $search = array('/\[b\](.*?)\[\/b\]/i',
                    '/\[i\](.*?)\[\/i\]/i',
                    '/\[u\](.*?)\[\/u\]/i',
                    '/\[url=(.*?)\](.*?)\[\/url\]/i',
                    '/\[code\](.*?)\[\/code\]/i',
                    '/\[img\](.*?)\[\/img\]/i',
                    '/\:D/i',
                    '/\:P/i',
                    '/\:\)/i',
                    '/\:\(/i',);
                    
    $h_toda_tml = array('<strong>$1</strong>',
                      '<i>$1</i>',
                      '<u>$1</u>',
                      '<a href="$1">$2</a>',
                      '<code>$1</code>',
                      '<img src="$1" alt="image" />',
                      '<img src="http://septimuswow.com/forums/public/style_emoticons/default/biggrin.gif" alt="grin" />',
                      '<img src="http://septimuswow.com/forums/public/style_emoticons/default/tongue.gif" alt="tongue" />',
                      '<img src="http://septimuswow.com/forums/public/style_emoticons/default/smile.gif" alt="smile" />',
                      '<img src="http://septimuswow.com/forums/public/style_emoticons/default/sad.gif" alt="sad" />',);

    $text = preg_replace($search, $h_toda_tml, $text);
    
    return $text;    
}
?>
Go wild, make your own arrays \o/, don't forget to change the smiley urls if you want to have your own.

How to install this?
First of all your page must include the page/script holding the bbcode system, if you save the above code as bbcode.php, you can include it like this:
PHP Code:
<?php include('bbcode.php');?>
How to use it?
To make stuff display using the BBcode system in the right BBcodes, you need to echo it by doing this:
PHP Code:
<?php echo bbcode('Hello guise, this text is [B]Bold[/B]! And this is [U]Underlined[/U]');?>
That would output:
Hello guise, this text is Bold! And this is Underlined
