Why would it get read into internal variables? In the code above you
never tell it to. Perhaps you meant:
function db() {
global $db;
$this->user = $db['user'];
$this->pass = $db['pass'];
}
Although I would add that you shouldn't really do this. It would be
preferable to do something like this instead:
function db($user, $pass) {
$this->user = $user;
$this->pass = $pass;
}
And pass in the values appropriately when you instantiate the object.
