How to change array for insert array data to database in PHP?

Question

My framework is Laravel 5.3, How to create array in HTML and insert array to Database in PHP?

For Example $passenger is 2.

In HTML:

@for($i = 1; $i <= $passenger; $i++)
<li id="passenger-adult-{{ $i }}">
    <fieldset>
        <legend>Passenger</legend>
        <div class="row">
            <div class="col-md-3 col-md-offset-3">
                <div class="form-group">
                    <label>Name</label>
                    <input class="form-control" type="text" name="name[]" required/>
                </div>
            </div>
            <div class="col-md-3">
                <div class="form-group">
                    <label>Family</label>
                    <input class="form-control" type="text" name="family[]" required/>
                </div>
            </div>
        </div>
        .
        .
        .
    </fieldset>
</li>
@endfor

After send passenger data Array is:

Array
(
  [_method] => PATCH
  [_token] => OwNvaXUvoGAKL25UN85GBiV7pN5I2ILEXw7vZrMa
  [name] => Array
    (
        [0] => amir
        [1] => ali
    )

  [family] => Array
    (
        [0] => hesari
        [1] => ahmadi
    )
  .
  .
  .
)

But! I need create array in this case, for insert to database:

Array
(
  [_method] => PATCH
  [_token] => OwNvaXUvoGAKL25UN85GBiV7pN5I2ILEXw7vZrMa
  [passenger] => Array
    (
        [name] => amir
        [family] => hesari
        .
        .
        .
    )

  [passenger] => Array
    (
        [name] => ali
        [family] => ahmadi
        .
        .
        .
    )
)

Answer 1

change this code

 <input class="form-control" type="text" name="name[]" required/>

to

  <input class="form-control" type="text" name="passenger[{{$i}}][name]" required/>

change this

<input class="form-control" type="text" name="family[]" required/>

to

<input class="form-control" type="text" name="passenger[{{$i}}][family]" required/>
