Laravel 5.6 - Pass additional parameters to API Resource?

This is how I made it on laravel 8.

class PatientResource extends JsonResource
{

  private static $data;
  /**
   * Transform the resource into an array.
   *
   * @param \Illuminate\Http\Request $request
   * @return array
   */
  public function toArray($request)
  {
    //access $data
    //self::$data
    return [
      'id' => $this->id,
      'first_name' => $this->first_name,
      'middle_name' => $this->middle_name,
      'last_name' => $this->last_name,
      'contact_number' => $this->contact_number
    ];
  }

  //I made custom function that returns collection type
  public static function customCollection($resource, $data): \Illuminate\Http\Resources\Json\AnonymousResourceCollection
  {
   //you can add as many params as you want.
    self::$data = $data;
    return parent::collection($resource);
  }
}

Then on my controller I called that custom function.

$data = PatientResource::customCollection($query->get(),$medicines);

The following approach worked for me:

UserResource

class UserResource extends Resource{

    protected $foo;

    public function foo($value){
        $this->foo = $value;
        return $this;
    }

    public function toArray($request){
        return [
            'id' => $this->id,
            'name' => $this->name,
            'foo' => $this->foo,
         ];
    }

    public static function collection($resource){
        return new UserResourceCollection($resource);
    }
}

UserCollection

class UserResourceCollection extends ResourceCollection{

    protected $foo;

    public function foo($value){
        $this->foo = $value;
        return $this;
    }

    public function toArray($request){
        return $this->collection->map(function(UserResource $resource) use($request){
            return $resource->foo($this->foo)->toArray($request);
    })->all();

        // or use HigherOrderCollectionProxy
        // return $this->collection->each->foo($this->foo)->map->toArray($request)->all()

        // or simple
        // $this->collection->each->foo($this->foo);
        // return parent::toArray($request);
    }
}

Different ways to pass the additional parameter

(new UserResource($user))->foo('bar');
(new UserResourceCollection($user))->foo('bar');

UserResource::make($user)->foo('bar');
UserResourceCollection::make($users)->foo('bar');
UserResource::collection($users)->foo('bar');
