Login script problem.

<?php	session_start();	if(!$_SESSION('logged_in')) {		echo "No user logged in.";	}	else {		echo "User logged in.";	}?>

Firstly I would like to check if a session is started yet before I call session_start(); but I don't know how to do that yet. Secondly when I am running this code $_SESSION('logged_in') is not defined yet which is as it should be however my code keeps turning up this error.

Fatal error: Function name must be a string in C:\inetpub\wwwroot\dsg\login.php on line 3

I can't seem to figure out why this error is coming up.

$_SESSION('logged_in') here $_SESSION is an associative array which will have something like $_SESSION['logged_in']

session starts only after session_start() if there is a active session passed it will resume to that session else it will start a new one.
