Regular Expression to remove URLs

[antriver]

Hi,
I'm trying to remove URLs from a string. I've got it to remove these formats of URLs:

google.com
www.google.com
http://www.google.com
http://google.com
http://example.google.com

$text = preg_replace("/(^¦\s)(http:\/\/)?(www\.)?[\.0-9a-zA-Z\-_~]+\.(com¦net¦org¦info¦name¦biz¦.+\.\w\w)((\/)?[0-9a-zA-Z\.\-_~#]+)?\b/ie","",$text);

The problem is that it is also taking out the plus symbol (+) from the text and anything written after an & gets removed.
e.g.

Testing + hello & blah

becomes

Testing hello

Thanks

Never mind, I've solved the problem. It wasn't this, I needed to urlencode the text in jquery before sending the ajax request.
