ช่วยดู Script ให้หน่อยครับมือใหม่ผมก็มึนๆทำหลายวันแล้วไม่ได้สักที

$btm1=$time-30;

            $res=mysql_query("select lottoo from lotto where time <'$btm1'");
			
            while($item=mysql_fetch_array($res))
            {
              $num1 = rand(1, 9);
			  mysql_query("update lo set lotto='$num1',time='$time'");
	mysql_query("update lotto set lottoo='$num1',time='$time'");
	
	$too=mysql_fetch_array(mysql_query("select id from lotto437 WHERE uid='".$ud."'"));
	$to=mysql_fetch_array(mysql_query("select money,lotto from lotto437 WHERE id='$too[0]'"));
	$lotto2=mysql_fetch_array(mysql_query("select lottoo from lotto"));
if ($to[1] == $lotto2[0]){ 
  $ugpl = mysql_fetch_array(mysql_query("SELECT plusses FROM users437 WHERE uid='".$ud."'"));
  $gpl = $to[0]*2;
  $ugpl = $gpl + $ugpl[0];
  mysql_query("UPDATE users437 SET plusses='".$ugpl."' WHERE uid='".$ud."'");
   echo "คุณถูกรางวัลและได้รับ ".number_format($gpl)." Coins.<hr/>";
mysql_query("delete from lotto437");
  } 
 
  }
