Question

我有一张桌子，上面有金额，director_id。我正在尝试通过添加相同的Director ID数量来创建数组，以便可以将其传递给Blade以创建表。但它会忽略每个ID的最后一个值。

贝勒是我的代码，但输出错误

$expense_details = DB::table('receipts')
            ->join('directors', 'directors.id', '=', 'receipts.director_id')
           ->join('account_type', 'account_type.id', '=', 'receipts.type')
            ->join('expense_type', 'expense_type.id', '=', 'receipts.exp_earn_type')

            ->select('receipts.*', 'directors.name as directors_name','account_type.name as account_name', 'expense_type.name as exp_name')
            ->get();

    dd($expense_details);



       $investor_total_by_id=[];

        $exp_amount=0;
      foreach ($expense_details as $exp){


          if (isset($investor_total_by_id[$exp->director_id])) {
              $exp_amount= $exp_amount + $exp->amount;
              $investor_total_by_id[$exp->director_id] = $exp_amount;

          }else {
              $investor_total_by_id[$exp->director_id] = $exp->amount;
          } 



       }

       //dd($investor_total_by_id);
        return view('Accounts/Investment/add')
             ->with('expense_details',$expense_details)
            ->with(' investor_total_by_id',  $investor_total_by_id)

        ;

表数组是这样的我正在尝试为每个Director_id分组/添加金额

    }
  ]
}

我得到这个结果

array:2 [▼
  1 => 7000.0
  2 => 7222.0
]

但应该是

array:2 [▼
  1 => 7100.0
  2 => 444.0
]

您将在整个循环中重复使用相同的$exp_amount变量，这就是为什么它会不断增大的原因。确实，您根本不需要它。只需将现有金额增加$exp对象中的金额即可。

foreach ($expense_details as $exp){
    if (isset($investor_total_by_id[$exp->director_id])) {
        $investor_total_by_id[$exp->director_id] += $exp->amount;
    } else {
        $investor_total_by_id[$exp->director_id] = $exp->amount;
    } 
}

我认为您也可以为此使用收集方法。

$investor_total_by_id = $expense_details->groupBy('director_id')->map(function ($expenses) {
    return $expenses->sum('amount'); 
});

如何通过对相同ID的值进行分组来创建新数组
