I'm sure this has been asked before, but at least not within the last 600 
messages (i checked):

I have the session variable $_SESSION['id'] set.  Well, I want to actually 
check the value of this variable, not just to check if it's set.  I would be 
doing this in a mysql query mainly.  Something like:

$result = mysql_query("select user from users where id = $_SESSION['id]", 
$db);

That just doesn't work, so I have to first go:

$sid = $_SESSION['id'];
$result = mysql_query("select user from users where id = $sid", $db);

Anyway to get around this?
