字符串中的转义字符

Question

我有一个嵌套循环，用于生成选项表单元素。 我试图让我的输出成为

round_1 [
  'playername' => 'id'
]

我相信我现在拥有的代码会胡说八道，因为当括号被传递到<select name=...语句时，括号并没有被转义。 其他一切正常。

有没有一种方法可以逃脱$ player并将其传递到PHP或Blade中的数组中？

我已经粘贴了代码的相关部分：

{!! Form::open(['url' => 'admin/games/process']) !!}

@foreach ($players_array as $game)
    <h4>Round {{$round}}</h4>
    <div class="form-group">

        @foreach($game as $player)
            <p><strong>{{ $player }}</strong></p>

            <!-- This chunk might be able to be written cleaner using laravelcollective/html -->
            <select name="round_{{$round}}[{{$player}}]">
                @foreach($all_players as $key=>$p)
                    <option value="{{ $key }}">{{ $p }}</option>
                @endforeach
            </select>

        @endforeach
    </div>
    <!-- {{ $round++ }} -->

@endforeach

<div class="form-group">
    {!! Form::submit('Submit Refactored Players', ['class' => 'btn btn-outline-primary form-control']) !!}
</div>
{!! Form::close() !!}

谢谢！

解决方案是使用str_replace替换]字符，将其传递到控制器中，然后创建一个新数组以通过反向替换放置旧数组，因为您无法可靠地更改php键。

视图

@foreach ($players_array as $game)
    <h4>Round {{$round}}</h4>
    <div class="form-group">

        @foreach($game as $player)
            <p><strong>{{ $player }}</strong></p>

            <!-- This chunk might be able to be written cleaner using laravelcollective/html -->
            <select name="round_{{$round}}[{{str_replace("]", "fstupidkey", $player)}}]">
                @foreach($all_players as $key=>$p)
                    <option value="{{ $key }}">{{ $p }}</option>
                @endforeach
            </select>

        @endforeach
    </div>
    <!-- {{ $round++ }} -->

@endforeach

控制者

public function process_logs(Request $request)
{
    /*
     * Accept player match arrays from user form
     * Input event data into database
     */


    $a = $request->round_1;

    /*
    * Create new array to put shit in..
    */
    $b = [];

    foreach($a as $key=>$item)
    {
        $c = str_replace("fstupidkey", "]", $key);
        $b[$c] = $item;
    }

    dd($b);

}
