Questoin. What's codesection in the code?

Holds the content of the text between [ code ][ /code ] before it's <br />'s and \n's are removed.

I went ahead and made a better parser. I personally think it works quite well, if you want to see it. I made it using completely RegExp, and you can modify it to your needs. It could also be used to create "noubbc" tags.



function ubbc($ext){
$ext = preg_replace("/\[code\](.+?)\[(.+?)\[\/code\]/i","[code]$1[$2[/code]",$ext);
$ext = preg_replace("/\[code\]\[(?!\/code)(.+?)\[\/code\]/i","[code][$1[/code]",$ext);
$ext = preg_replace("/\[code\](.+?)\](.+?)\[\/code\]/i","[code]$1]$2[/code]",$ext);
$ext = preg_replace("/\[code\](.+?)(?!\/code)\]\[\/code\]/i","[code]$1][/code]",$ext);
$ext = preg_replace("/\[code\](.+?)\[\/code\]/i","<table border=\"1\"><tr><td>$1</td></tr></table>",$ext);
return $ext;
}

Here is a preview

The inputted info is [code][b]test[/b][/code][b]test2[/b]. Of course, I added a function for bold tags.
