Reg Ex to search for both Integer and Comma-spaced Integer

I'm a little confused by something. I need to build a reg-ex to scrape for both plain integers and comma spaced integers in the same place in the same string at the same time. For example.. $string = "Mark's average score was 544."; preg_match("/average score was ([0-9]+)/", $string, $matches); $score = $matches(1); $string = "Julie's average score was 10,443."; preg_match("/average score was ([0-9]+,[0-9]+)/", $string, $matches); $score = $matches(1); How do I combine these two queries so that the reg-ex matches both the comma spaced integer and regular integer? Thanks! - Kevin
