From Mike: > $middlenum = > preg_replace("/^${this->start_num}(.*)${this->end_num}$/", '$1', > $this->ach_acct_num); From John: > $new_number = > > preg_replace('/^'.$this->start_num.'([0-9]+)'.$this->end_num.'$/', '\\1',$old _number); The one that Mike gave didn't seem to do anything, John's will work if it can match the beginning and the end successfully. I should probably explain myself further. Sometimes there won't be anything to replace at the front, and sometimes nothing at the end. So it'd still need to do the front and/or end wether or not they both exist. Is there a way to tweak these to do that? -Dan Joseph
