发生此错误是因为您将普通变量视为数组。尝试重命名表单元素，如下所示：
"spa_order_desc"到"spa_order_desc[]"
"spa_order_qty"到"spa_order_qty[]"
"spa_order_unit_prc"到"spa_order_unit_prc[]"
"spa_order_amt"到"spa_order_amt[]"
此外，将插入查询放在循环中，以便为上一步中的每个输入插入。
for($i=0; $i < count($spa_order_desc1); $i++) {
$spa_order_desc = $spa_order_desc1[$i];
$spa_order_qty = $spa_order_qty1[$i];
$spa_order_unit_prc = $spa_order_unit_prc1[$i];
$spa_order_amt = $spa_order_amt1[$i];
$insert_spa_o_dtl=mysql_query("INSERT INTO tb_spa_order_details(spa_order_desc,spa_order_qty,spa_order_unit_prc,spa_order_amt) VALUES('$spa_order_desc','$spa_order_qty','$spa_order_unit_prc','$spa_order_amt')");
