การ fetch ข้อมูลจาก result ที่คิวรี่ได้จะอ้าง index ของ array ได้ยังไง หรือใครมีวิธีแก้ไขอื่นๆแนะนำหน่อยคับ

while($row = mysql_fetch_assoc($result)){
	$rec += 1;
	$sum += $row['num_ps2']*$row['price_one'];
	$line += 1;
	if(mb_strlen($row['name_ps2'],"UTF-8") > 55){
		$arr = explode(" ",$row['name_ps2']);
		$numlen = 0;
		for($a=0;$a<count($arr);$a++){;
		echo $arr[$a].' ';
			$numlen += mb_strlen($arr[$a],"UTF-8");
			if($a != count($arr)-1){
				$numlen += 1;	//whitespace
				if(mb_strlen($arr[$a+1],"UTF-8")+$numlen > 55){
					$numlen = 0;
					$addline += 1;
					$line += 1;
				}
			}
		}
	}echo $rec.' '.$line.'<br>';
	if($line/21 > 1 || $line%21 == 0){
		if($line > 21){$rec -= $line-21;}
		$addline += $line-21; 
		$line = 0;
		$minus[$x] = 21-$rec;
		$x += 1;
		$rec = 0;
	}
}

if($j!=0){$strminus += $minus[$x-1];}
		$str = "SELECT name_ps2,num_ps2,unit,year_ps2,date_use,price_one,price_two,type_budget,date_ps2,type_material,for_use,balance,vat FROM ps2 x,ps2_h y WHERE x.no_paper = y.no_paper and x.no_acc = y.no_acc and x.no_paper = \"".$_GET['p']."\" and x.no_acc = \"".$_SESSION['chk_no_acc']."\" and division = \"".$_SESSION['chk_division']."\" ORDER BY name_ps2 LIMIT ".((0+(21*$j))-$strminus).",".(21-$minus[$x]);
