有什么功能可以停止foreach循环吗？

Question

每当我尝试打印表格时，我都会建立一个循环，第一行打印良好并带有类别名称，然后第二行打印具有一个tr（row）数据的表并关闭标签，然后再次开始新行并打印下一个数据一行...

我想根据类别名称打印所有数据而不会破坏多张表

@if( ! empty($packages) )
    @php
        $serviceId=null;
    @endphp
    @foreach($packages as $package)
        @if(is_null($serviceId))
        <!--CATEGORY NAME PRINT-->
        <div class="row" id="">
          <div class="col-sm-12">
            <div class="well wellHeader">
              <h2>{{ $package->service->name }}</h2>
            </div>
          </div>
        </div>
        <!--CATEGORY NAME PRINT-->
        @php
            $serviceId=$package->service->id
        @endphp

        @endif

        @if($serviceId != $package->service_id)
        <!--CATEGORY NAME PRINT-->

您可以创建一个额外的数组来映射它，

在方法中

$packagesNew = [];
foreach($packages as $k => $v)
{
  $packagesNew[$v->service->name]['name'] = $v->service->name;
  $packagesNew[$v->service->name]['id'] = $v->service->id;
  $packagesNew[$v->service->name]['service_id'] = $v->service_id;
  $packagesNew[$v->service->name]['data'][] = $v;
}

通过packagesNew来查看

然后，我对视图进行了更改，请检查。

@if( ! empty($packagesNew) )
@php
$serviceId=null;
@endphp
@foreach($packagesNew as $k => $package)
@if(is_null($serviceId))
