If you include vB's global.php on your php page, it basically does what you're looking for I'm pretty sure.

PHP Code:

// Near or at the begining of the php file
require_once('./global_stock.php'); 


Then something like this....

PHP Code:

if ($bbuserinfo['userid']){
// If they are logged in, then do this
//stuff here
}
else{
// If they aren't logged in, do something else here.
} 


.... furthermore... (correct me if I'm wrong), but you can do a check to see if someone ISN'T logged in by adding an exclamation mark...

PHP Code:

if (!$bbuserinfo['userid']){

}
