Just a side note to nel, if you are going to use shimmyshack's U
modifier you have to use PCRE instead as Rik is doing, and be sure not
to copy Rik's exact pattern unless you switch because you are using
PHP's built in regex functions.
At least, I think you are using PHP's built-in regex stuff, assuming
that by regi_replace() you mean eregi_replace()
