PHP call_user_func_array：如何将所有参数作为单个数组传递？

Question

I am using call_user_func_array in an MVC structure to point to a controller and method and pass the parameters of the URL:

// At this point, $url is an array with nothing but parameters

$this->params = $url ? array_values($url) : []; //

call_user_func_array([$this->controller, $this->method], $this->params); 

Now when I use this:

class Home extends Controller {

    public function index($param1=null, $param2=null) { // Ugly...

      // .. continue

Is there any way to send all the parameters to the class method as one single array? There's no telling if there are any parameters to begin with, and if there are, there's no telling how many. I don't want to have to do:

public function index($param1=null, $param2=null, $param3=null, $param4=null) {

I'm looking to do:

public function index($params) {

  if (isset($params[0])) {

It is obviously:

call_user_func_array(
    [$this->controller, $this->method], 
    [$this->params]
);
