Re: Question on variable variables

Yes trying to get this to work: $curline = preg_replace("/<yabb\s+(\w+)>/","$$1",$curline); So for the current line I am looking for something like <yabb copyright> I want to replace that with the contents of $copyright. Can variable variables be used in regular expressions?
