Accessin array outside function?

I have a fuction that pulls an array from a mySQL database for Joomla!

But, how do i access that array outside my fucntion? My code doesnt work, as $rows is "NULL" when i try to act on it outside the function.

<?
defined('_VALID_MOS') or die('Direct access to this location not allowed');
 
getSessions();
//var_dump($rows);
foreach ( $rows as $row) {
	echo "$row->title $row->session_up\n";
}
 
function getSessions(){
	global $database;
	$sql= "select * from #__events_sessions where title like 'Stamps%' and session_down > now() order by session_up limit 1";
	$database->setQuery($sql);
	$rows = $database->loadObjectList();
	var_dump($rows);
//	foreach ( $rows as $row ) {
//		echo "$row->title $row->session_up\n";
//	}
	return $rows;
}
 
?>
