I used this code to pull info from the database and into the array.
Code:
$stu_quary = "SELECT `uname` FROM `user` WHERE level = 'Normal' AND class = '".$_SESSION['class']."'"; 
	$stu_names=mysql_query($stu_quary);
	$stuArr=array();
	while($get_stu_info =mysql_fetch_assoc($stu_names)) 
	{ 
	$n = 0;
    $stuArr[] = $get_stu_info['uname']; 
	$_SESSION['selected_s'] = current($stuArr);
