Basically, there are libraries out there like jQuery which make it easy to do what it is you are wanting.

How it will work:

Let's say you have a <div></div> container for the portion of the page that displays your score stuff that needs to be updated. In that <div></div> you need the contents of showscores.php which has the score information. Your ajax script will pull that information and replace whatever is in that <div></div> with the new content. You'll set a repeating timer to do this on a set interval. This means that every x number of seconds, your ajax script will get the contents of showscores.php and put it into the <div></div>. If there was a change, your users will see the change.

Going the ajax route will require that your users have javascript capable browsers and that javascript is enabled.

There is another option called reverse ajax, but it requires special software to implement. Depending on your server configuration, this may not be a viable option.

If you ask more precise questions you'll get more precise answers.

SEMPER FIDELIS!

I can't stop you from doing something silly, but at least I can help you do it right.
