在 foreach 中查找第一项？

Question

我正在尝试添加 class 'active' if 这是 foreach 中的第一项，但我一直收到解析错误？我正在使用 Laravel 和 Blade，这就是我传递 $members

的方式

public function getView()
    {
        Cache::remember('members.members', 1, function() {
            return Player::orderBy('id', 'DESC')->where('display_member', '=', '1')->limit(10)->get();
        });

        return view('frontend.members')->withMembers(Cache::get('members.members'));
    }

Parse error: syntax error, unexpected 'endforeach' (T_ENDFOREACH), expecting elseif (T_ELSEIF) or else (T_ELSE) or endif (T_ENDIF)

<div class="tab-content">
    @if ($members->count() > 0)
        @foreach ($members as $key => $member)
        <div role="tabpanel" class="tab-pane @if($members->first() == $member)active@endif" id="{{ $member->username }}">
            <div class="col-md-12">
                <h1>{{ $member->username }}</h1>
                <br>
                <p>Personal Website: <a href="{{ $member->personal_website }}">{{ $member->personal_website }}</a></p>
                <p>Last Login: 1st January, 2017</p>
            </div>
        </div>
        @endforeach
    @endif
</div>

Answer 1

如果你的版本laravel 5.3:

@foreach($array as $key => $value)
    @if ($loop->first)
        ...
    @endif
@endforeach

Answer 2

@foreach($array as $key => $value)
 @if ($key == 0)
    .....
 @endif
@endforeach
