您可以在MySQL查询中完全处理它：
SELECT SUM(column_name) FROM table_name;
$result = MysqL_query('SELECT SUM(value) AS value_sum FROM codes');
$row = MysqL_fetch_assoc($result);
$sum = $row['value_sum'];
使用PDO（MysqL_query已弃用）
$stmt = $handler->prepare("SELECT SUM(value) AS value_sum FROM codes");
$stmt->execute();
$row = $stmt->fetchAll(PDO::FETCH_OBJ);
$sum = $row->value_sum;
