Well in that case you probably want something like this (after you've
checked to see whether the user is logged in etc):
$sql = "UPDATE users SET money = money - 10 WHERE id = " .
$_SESSION['user_id'];
assuming of course that you have a table called users where the money
for each one is stored and you're keeping the user_id in the $_SESSION
superglobal.
It's a bit difficult to help further without a bit more information. :)
