Function won't work

[Mutley]

$time = time();
function userOnline($useronline) {
// Check if user is online:
	$result_online = mysql_query("SELECT online FROM users WHERE user_id = '$useronline' LIMIT 1");
	while($row_online = mysql_fetch_array( $result_online ))
    	{
	$online = $row_online['online'];
	}

	if($time - $online < 30) {
	echo "<img src=\"images/online.gif\" alt=\"Online\" /> ";
	} else {
	echo "<img src=\"images/offline.gif\" alt=\"Offline\" /> ";
	}
// End check				
}

 

Then when I use the function it always says there online? However the code works out of function.

$time = time(); needs to be inside your function or you have to use global $time

Thanks. Fixed.
