正确显示关联数组的结果 Laravel/PHP

Question

我正在尝试在 Laravel 中显示来自查询的名称列表，但无法正确显示结果。

这是我的控制器中的内容：

public function getSettings()
{
    $contents = explode(",", File::get(storage_path('app/public/users/0/config/social_module/buddy.txt')));
    foreach($contents as $key => $value){
        $buddylist[$value] = User::select('fullname as name')->where('id', $value)->get();
    }
    return view('welcome', compact('buddylist'));
}

这是我的看法：

    @foreach($buddylist as $buddy)
    <ul>
        <li>{{ $buddy }}</li>
    </ul>
    @endforeach

如果我使用 $buddy=>$key 它什么也不显示。 如果我改用它，结果如下所示：

[{"name":"Alix Earnshaw"}]
[{"name":"Horacio Esgate"}]
[{"name":"Patrizia Anthony"}]
[{"name":"Ann-marie McLewd"}]
[{"name":"Boote Poulsum"}]
[{"name":"Any Bandy"}]
[{"name":"Francene Lelliott"}]
[{"name":"Ingelbert Abdy"}]
[{"name":"Nickolaus Di Biaggi"}]
[{"name":"Constantina Wreight"}]
[{"name":"Clarissa Coomer"}]

print_r($contents)

Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 [5] => 12 [6] => 43 [7] => 74 [8] => 23 [9] => 67 [10] => 32 ) 

print_r($buddylist)

Answer 1

使用first() 代替get() -

$buddylist[$value] = User::select('fullname as name')->where('id', $value)->first();

在你看来——

@foreach($buddylist as $buddy)
<ul>
    <li>{{ $buddy->name }}</li>
</ul>
@endforeach
