PHP 5.4.17替代"...运算符" [英] PHP 5.4.17 alternative for the "... operator"

问题描述

我想知道是否有人会知道PHP 5.6.x和更高版本的...运算符(或我相信它称为splat运算符)的替代方法.

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).

我当前在PHP 7版本中所做的是:

What i'm currently doing in my PHP 7 version is:

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

callAction()函数具有2个参数callAction($controller, $action)，但是现在我需要将代码降级为PHP 5.4.17.

The callAction() function takes 2 parameters callAction($controller, $action) but now I need to downgrade the code to PHP 5.4.17.

推荐答案

尽管splat运算符...与call_user_func_array()相似:

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]]));

我认为传递必需的参数会更有意义:

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);
