如何獲取陣列的第一個和第二個元素？下面是我的物件Tour陣列資料。
某些 Tour 可能沒有tour_attendees（空陣列）。
#items: array:3 [▼
0 => {#2115 ?}
1 => {#3067 ?}
2 => {#2125 ▼
"id": 12
"schedule_date": "28-11-2021"
"created_at": "2021-11-18T00:16:42.000000Z"
"updated_at": "2022-01-19T08:29:05.000000Z"
"deleted_at": null
"tour_attendees": array:2 [▼ // array data that I want to extract
0 => {#3077 ?} // attendee #1
1 => {#3054 ?} // attendee #2
]
}
我想提取資料并放入下表中。
| No | Attendee #1 | Mobile | Attendee #2 | Mobile |
| | | (Attendee #1) | | (Attendee #2) |
|-----|----------------|-----------------|------------------|-----------------|
| 1 | | | | |
| 2 | | | | |

@foreach ($tour->tour_attendees as $key => $value)
<td>
@if (!empty($tour->tour_attendees))
@foreach ($tour->tour_attendees as $key => $attendee)
@if ($key == 0)
{{ $attendee->name }}
@endif
@endforeach
@endif
</td>
<td> attendee #1 mobile</td>
@endforeach

您可以將陣列包裝在集合中，并且只獲取兩條記錄，如下所示：
collect($your_array)->take(2)->get()

您可以使用forelse并break打開key === 2
@forelse ($tour->tour_attendees as $key => $attendee)
@if ($key === 2)
@break
@endif
<td>
{{ $attendee->name }}
</td>
<td>
{{ $attendee->mobile }}
</td>
@empty
<td> - </td><td> - </td><td> - </td><td> - </td>
@endforelse
@if (count($tour->tour_attendees) === 1)
<td> - </td><td> - </td>
@endif

您還可以使用以下array_splice()功能：
$tour_attendees = array_splice($yourArray,0,2);
