การเก็บค่าผลรวมที่เป็น array ลงฐานข้อมูล ต้องเขียนยังไงดีคะ

<?php
$host= 'localhost';
$user = 'root';
$pwd = '1234';
$db = 'intern';

$con_nect = mysql_connect($host,$user,$pwd) or die (mysql_error());
mysql_select_db($db);

$sql = "SELECT loc2_q1, loc2_q2, loc2_q3, loc2_q4, loc2_q5, loc2_q6, loc2_q7, loc2_q8, loc2_q9, loc2_q10 FROM ass_location2 ";
$query = mysql_query($sql);
$row = mysql_num_rows($query);
if($row > 0){
   $loc2_sum = array();
   
    while($rs = mysql_fetch_array($query)){
             $q1 = $rs['loc2_q1'];
             $q2 = $rs['loc2_q2'];
             $q3 = $rs['loc2_q3'];
             $q4 = $rs['loc2_q4'];
             $q5 = $rs['loc2_q5'];
             $q6 = $rs['loc2_q6'];
             $q7 = $rs['loc2_q7'];
             $q8 = $rs['loc2_q8'];
             $q9 = $rs['loc2_q9'];
             $q10 = $rs['loc2_q10'];

             $loc2_sum[] = $q1+ $q2+ $q3+ $q4+ $q5+ $q6+ $q7+ $q8+ $q9+ $q10;

    } // end while
              print_r($loc2_sum);
}else{
    echo "Not Found.";
}
?>
