Note that register_globals can be turned off, and is off by default in later PHP versions as it's considered a bad practice. Use $_GET superglobal instead.

Also don't forget to validate the user input. In this case id is integer value so the correct access should be:
[php]
$id=(int)$_GET['id'];
[/php]

If it's not numerical, use mysql_real_escape_string() before putting them into your queries.
