在 laravel 中添加两个整数

Question

基本上我想要的是将两个数字相加并求和。

这是我的代码：

if (isset($this->date_filed) && !empty($this->date_filed) && !empty($this->date_forwarded_to_cmt_contractor)) {
            $date_forwarded_to_cmt_contractor = Carbon::createFromFormat('Y-m-d', $this->date_forwarded_to_cmt_contractor);
            $date_filed = Carbon::createFromFormat('Y-m-d', $this->date_filed);
            $interval = $date_filed->diff($date_forwarded_to_cmt_contractor);
            $this->cst_to_cmt = $interval->format('%a' . ' ' . 'Days');

            if ($this->status == 'RECTI03') {
                $now = Carbon::now();
                $date_forwarded_to_cmt_contractor = Carbon::createFromFormat('Y-m-d', $this->date_forwarded_to_cmt_contractor);;
                $interval = $date_forwarded_to_cmt_contractor->diff($now);
                $this->cmt_to_current_date = $interval->format('%a' . ' ' . 'Days');

            }

            $this->date_filed_to_current_date = $this->cst_to_cmt + $this->cmt_to_current_date;

        }

这是我尝试添加它们的部分。

$this->date_filed_to_current_date = $this->cst_to_cmt + $this->cmt_to_current_date;

但是我收到了这个错误。为什么？ :/

"A non well formed numeric value encountered"

将类型转换为 integer 怎么样？

$this->date_filed_to_current_date = (int)$this->cst_to_cmt + (int)$this->cmt_to_current_date;

如果数字中包含逗号或任何其他不需要的非数字字符，例如字符串中的 , 或 -，那么您将收到通知 A遇到格式不正确的数值 所以最好在添加操作之前将其转换为整数类型。
