How to get (use) an array of parameters call_user_func_array?

Question

PHP

Anyway, back to one question..
In the index.php entry point, I run the application class...
$app=new App();
in the App class in the constructor

public function __construct (){
...
call_user_func_array([$this->controller,$this->method],$this->params);
}

address:
localhost/myproj/map(controller)/lal(method)/foo(parameter_1)/bar(parameter_2)
In the controller, example:

public function lal($param1=NULL,$param2) {
    echo $param1; //foo
    echo $param2; //bar
  }

Is it possible to get all the parameters in an array? Or is the only way to pass it to the controller's constructor when instantiating it?

https://wiki.php.net/rfc/argument_unpacking
n PHP 5.6 and later, argument lists may include the ... token to denote that the function
accepts a variable number of arguments. The arguments will be passed into the given variable as an array; for example:
Example #13 Using ... to access variable arguments
<?php
function sum(...$numbers) {
$acc = 0;
foreach ($numbers as $n) {
$acc += $n;
}
return $acc;
}
echo sum(1, 2, 3, 4);
?>
