รบกวนเช็คโค้ดให้หน่อยครับ Query เยอะ loop เยอะมากครับ

<? include('config.php'); 
$w1 = 1;

$sa1 = $mysqli->query("SELECT * FROM plot WHERE admin_id = '".$_SESSION['idn']."' ORDER BY pl_id DESC LIMIT 50");
while($saa1=$sa1->fetch_assoc()){ $i2 = $i2 + 1; ?>

<tr>
	<td style="padding-top: 5px">
<input type="checkbox" class="form-control" name="chkDel[]" id="chkDel<?= $i2;?>" value="<?= $saa1["pl_id"];?>">
</td>

	<td><center><p style="margin: 0px 0px"><?= $w1; ?></p></center></td>

	<td><center><p style="margin: 0px 0px">PL<?= $saa1['pl_id']; ?></p></center></td>

	<? $yy1 = $mysqli->query("SELECT * FROM province WHERE pro_id = '".$saa1['pro_id']."'");											 
       $y1 = $yy1->fetch_assoc(); ?> 
	<td><center><p style="margin: 0px 0px"><?= $y1['pro_name']; ?></p></center></td>

	<? $yy2 = $mysqli->query("SELECT * FROM district WHERE dis_id = '".$saa1['dis_id']."'");											 
       $y2 = $yy2->fetch_assoc(); ?> 
	<td><center><p style="margin: 0px 0px"><?= $y2['dis_name']; ?></p></center></td>

	<? $yy3 = $mysqli->query("SELECT * FROM subdis WHERE sub_id = '".$saa1['sub_id']."'");											 
       $y3 = $yy3->fetch_assoc(); ?> 
	<td><center><p style="margin: 0px 0px"><?= $y3['sub_name']; ?></p></center></td>
						
	<td><center><p style="margin: 0px 0px"><?= $saa1['pl_moo'];?></p></center></td>
	<td><center><p style="margin: 0px 0px"><?= $saa1['pl_position'];?></p></center></td>
	<td><center><p style="margin: 0px 0px"><?= $saa1['pl_name'];?></p></center></td>
</tr> 
<? $w1++; } $mysqli->close(); ?>
