php - 如何在 Laravel 或 Php 中手动增加获取的数据值？

Question

使用 Laravel 5.8我只想从表中获取 work_order_no 并将其加 1 并将该值存储到另一个变量。

$statement = DB::select('select work_order_no from work_order where id = 1');
//$won = $won_id->work_order_no+1;
$nextId = intval($statement[0])+1;
$won = $nextId;

显示错误 -stdClass 类的对象无法转换为 int

试试这个。

$statement = DB::table('work_order')->select('work_order_no')->where('id',1)->first();
$nextId = intval($statement->work_order_no) + 1;
$won = $nextId;
