$x=0;
//while $i is smaller than number of rows repeat the code
while ($i < $rows) {
$online=mysql_result($chars,$i,"online"); //looks into characters table, under column online(if player is online its "0" else "1"), at row $i
if ($online == 1) { $x++; } // if column online at row $i is "1", increase $x

}
print 'Online players:<em>'.$x.'<em>'; //prints out the $x number of players online
