Problem with RegEx for BBCode

Hi all, I am playing around with PHP and BBCodes and have found some regex's that should transform my BBCode into correct HTML when rendering. However, I have found that if the BBCode is not correct (eg missing closing tag), the regex completely eats my input and my page is empty! The regex I'm using is: /\[i\]((\s|.)+?)\[\/i\]/ And with an input like: This is [i]italic. I get nothing back. What I would like is that when no closing tag is found, the opening tag should just be shown as-is. Anybody have any idea how I can do this?
