如何在PHP中干净地迭代数组

你好，我在迭代我的数组时遇到了困难。我不知道如何使用简单的

foreach

或

foreach

和

$key

。我试过按

键

，但我有一个错误：

非法字符串偏移“payroll\u employee\u company\u id”（视图：/var/www/html/digimahouse/resources/views/member/payrollreport/loan\u summary\u table.blade.php）

我怎样才能成功地迭代它

这是我的数组

这是我的名片

 @foreach($totals as $key => $total)
      @if($total['payroll_employee_company_id'] == $comid->payroll_company_id)
        <tr class="total">
          <td class="text-center"><strong>TOTAL</strong></td>
          <td class="text-center"></td>
          <td class="text-center"></td>
          <td class="text-center">{{$total['loan_total']}}</td>
          <td class="text-center">{{$total['total_total_payment']}}</td>
          <td class="text-center">{{$total['total_remaining_balance']}}</td>
          <td class="text-center"></td>
        </tr>
    @endif
@endforeach

您的foreach不在正确的数组中

 @foreach($data['totals'] as $key => $total)
  @if($total['payroll_employee_company_id'] == $comid->payroll_company_id)
    <tr class="total">
      <td class="text-center"><strong>TOTAL</strong></td>
      <td class="text-center"></td>
      <td class="text-center"></td>
      <td class="text-center">{{$total['loan_total']}}</td>
      <td class="text-center">{{$total['total_total_payment']}}</td>
      <td class="text-center">{{$total['total_remaining_balance']}}</td>
      <td class="text-center"></td>
    </tr>
@endif

@foreach（$data['totals']as$key=>$total）
@如果（$total['payroll\u employee\u company\u id']=$comid->payroll\u company\u id）
总计
{{$total['loan_total']}
{{$total['total_total_payment']}
{{$total['total_剩余_余额']}

@endforeach

您已经说过图片是

{{dd（$totals）}

的结果。在这种情况下，请执行以下操作：

@foreach($totals['totals'] as $key => $total)
      @if($total['payroll_employee_company_id'] == $comid->payroll_company_id)
        <tr class="total">
          <td class="text-center"><strong>TOTAL</strong></td>
          <td class="text-center"></td>
          <td class="text-center"></td>
          <td class="text-center">{{$total['loan_total']}}</td>
          <td class="text-center">{{$total['total_total_payment']}}</td>
          <td class="text-center">{{$total['total_remaining_balance']}}</td>
          <td class="text-center"></td>
        </tr>
    @endif
@endforeach

@foreach（$totals['totals']作为$key=>$total）
@如果（$total['payroll\u employee\u company\u id']=$comid->payroll\u company\u id）
总计
{{$total['loan_total']}
{{$total['total_total_payment']}
{{$total['total_剩余_余额']}
@恩迪夫
@endforeach

总计$totals从哪里来？发帖…@B001顺便说一句，你的意思是：不要使用@？？这是一种拉维语法。在控制器中。@AbdullaNilam完全是我的错…你在循环哪个？数组内的总计或包含页面、\u company、\u load\u data和totals的整个数组？他实际上返回

$totals

变量，而不是

$data

。这就是

view（）

助手的工作原理。先生，您能解释一下它为什么工作吗？我想理解我的错误。@nethkennn你只要把它嵌套两次就行了。您还可以执行以下操作

array\u marge（$data，$this->get\u totals\u loan\u summary（$data））

使以前的代码在视图中工作。

@foreach($totals['totals'] as $key => $total)
      @if($total['payroll_employee_company_id'] == $comid->payroll_company_id)
        <tr class="total">
          <td class="text-center"><strong>TOTAL</strong></td>
          <td class="text-center"></td>
          <td class="text-center"></td>
          <td class="text-center">{{$total['loan_total']}}</td>
          <td class="text-center">{{$total['total_total_payment']}}</td>
          <td class="text-center">{{$total['total_remaining_balance']}}</td>
          <td class="text-center"></td>
        </tr>
    @endif
@endforeach
