【问题描述】：

我需要计算查询中列中的日期与循环内的今天之间的差异，以收集装运的年龄

我尝试使用 datediff 将发货日期作为第一个参数，将 today() 作为第二个参数

@foreach($shipments as $shipment)
    <tr>
        <td data-title="id">{{$shipment->id}}</td>
        <td class=tracking data-title="tracking">{{$shipment->tracking}}</td>
        <td data-title="PartNumber">{{$shipment->PartNumber}}</td>
        <td data-title="DateShipped">{{$shipment->DateShipped}}</td>
        <td data-title="age" value={{$shipment->DateShipped}}-today()><?php echo date_diff({{$shipment->DateShipped}},today())?></td>
        <td data-title="Qtyorder">{{$shipment->Qtyorder}}</td>
        <td data-title="QtyShipped">{{$shipment->QtyShipped}}</td>
        <td data-title="QtyBckorder">{{$shipment->QtyBckorder}}</td>
        <td data-title="purchaseOrder">{{$shipment->purchaseOrder}}</td>
        <td data-title="OrderNumber">{{$shipment->OrderNumber}}</td>
        <td value={{$shipment->Location}}>{{$shipment->Location}}</td>
        <td data-title="paperwork">{{$shipment->paperwork}}</td>
        <td data-title="VMIreceived">{{$shipment->VMIreceived}}</td>
        <td data-title="VMIticketNumber">{{$shipment->VMIticketNumber}}</td>
        <td data-title="VMILRB">{{$shipment->VMILRB}}</td>

        <td><a href="{{ route('shipment.edit',$shipment->id)}}" class="btn btn-primary">Edit</a></td>
        <td>
            <form action="{{ route('shipment.destroy', $shipment->id)}}" method="post">
                @csrf
                @method('DELETE')
                <button class="btn btn-danger" type="submit">Delete</button>
            </form>
        </td>
    </tr>
@endforeach

@foreach($shipments as $shipment)
<tr>
    <td  data-title="id">{{$shipment->id}}</td>
    <td class=tracking data-title="tracking">{{$shipment->tracking}}</td>
    <td data-title="PartNumber">{{$shipment->PartNumber}}</td>
    <td data-title="DateShipped">{{$shipment->DateShipped}}</td>
    <td data-title="age" data-value="{{(int) floor((time() - strtotime('2019-04-29')) / (60 * 60 * 24))}}"></td>
    <td data-title="Qtyorder">{{$shipment->Qtyorder}}</td>
    <td data-title="QtyShipped">{{$shipment->QtyShipped}}</td>
    <td data-title="QtyBckorder">{{$shipment->QtyBckorder}}</td>
    <td data-title="purchaseOrder">{{$shipment->purchaseOrder}}</td>
    <td data-title="OrderNumber">{{$shipment->OrderNumber}}</td>
    <td value={{$shipment->Location}}>{{$shipment->Location}}</td>
    <td data-title="paperwork">{{$shipment->paperwork}}</td>
    <td data-title="VMIreceived">{{$shipment->VMIreceived}}</td>
    <td data-title="VMIticketNumber">{{$shipment->VMIticketNumber}}</td>
    <td data-title="VMILRB">{{$shipment->VMILRB}}</td>

    <td><a href="{{ route('shipment.edit',$shipment->id)}}" class="btn btn-primary">Edit</a></td>
    <td>
        <form action="{{ route('shipment.destroy', $shipment->id)}}" method="post">
            @csrf
            @method('DELETE')
            <button class="btn btn-danger" type="submit">Delete</button>
        </form>
    </td>
</tr>
@endforeach

它会给你天数的差异（例如 24-48 小时将显示 1 天，48-72 将显示 2 天）

(60 * 60 * 24) 这是minute * second * day, 如果您想以小时为单位显示差异，例如删除day，您将获得小时差异（60 * 60 而不是 60 * 60 * 24）

如果有效，点击这个答案是正确的:)
现在我修改了你的答案以使用前一个单元格中的值，这正是我想要做的

【解决方案2】：

Carbon 支持human readable difference:

<td>{{ $shipment->DateShipped->diffForHumans() }}</td>
