Laravel change request input from string to array

I'm building an API with custom query filter, in my filter, there are rules that value cannot be empty and some fields has to be an array.

I have managed to filter out empty fields if they are submitted but I can't convert request input to the array, is there a way to do it?

Here is my code: 

public function removeEmptyFieldsFromRequest($request)
{

    $emptyFields = [];

    foreach ($request->all() as $name => $value)
    {
        if (is_null($value)){
            $emptyFields[] = $name;
        }


        $fields = ['transmissions', 'grades', 'colors', 'equipment', 'lots', 'chassis', 'auctions', 'models'];

        if (in_array($name, $fields)){

           // here need to convert request value from a string into the array
        }


    }

    $request = $request->except($emptyFields);

    return $request;
}

I want to make this filter usable in different cases, I know that I can change the input name to the array on the front end

if you query string is like this : /?a=1&b=2&a=3&c=1&a=2.

You can create a function that parses the query string something like this: 

$uri = explode('?', Request::capture()->getRequestUri());
$queryStringArr = explode('&',$uri[1]);
$params = [];
foreach ($queryStringArr as $item) {
    $i = explode('=',$item);
    if (!empty($params[$i[0]])){
        $params[$i[0]]=array_merge((is_array($params[$i[0]]))?$params[$i[0]]:[$params[$i[0]]],[$i[1]]);
    }else{
        $params[$i[0]]=$i[1];
    }
}
print_r($params);die;

Which gives.

Array
(
    [a] => Array
        (
            [0] => 1
            [1] => 3
            [2] => 2
        )

    [b] => 2
    [c] => 1
)

I haven't tested it much so give it a thought yourself.

In Laravel if your parameters is like field[0],field[1],...
you can get it with $request->field and it is array so you can check 

is_array($request->field)

and in your case you can check it with below code

is_array($value)
