PHP 5.4.17 alternative for the “… operator”

Question

I was wondering if someone may know an alternative to the PHP 5.6.x and higher ... operator (or splat operator I believe its called).

What i\'m currently do

Answer 1

Though the splat operator ... is similar to call_user_func_array():

call_user_func_array(array($this,'callAction'),
                     explode('@', $this->routes["authControllers"][$this->routes["uri"][$uri]]));

I think it would make more sense to pass the required arguments:

list($controller, $action) = explode('@', $this->routes["authControllers"][$this->routes["uri"][$uri]]);
$this->callAction($controller, $action);
