如何使用PHP在过程的中间重新加载页面

Question

这是我的代码：

public function save_problem(Request $request)
{
    $doesnot_turn_on = isset($request->doesnot_turn_on) ? $request->doesnot_turn_on : "";
    $res = setcookie('guarantee_ticket', json_encode(["title"=>$request->problem_title, "description"=>$request->problem_description, "turn_on" => $doesnot_turn_on, "unique_product_id" => $request->unique_product_id]), time() + 200000, "/");
    if ( Auth::check() ){
        return $this->register_guarantee_ticket();
    } else {
        return redirect()->route('short_register',["des" => route('register_guarantee_ticket')]);
    }
}
public function register_guarantee_ticket()
{
    $problem = json_decode($_COOKIE['guarantee_ticket']);
    .
    .

您可以看到，当Auth::check()为true时，将调用register_guarantee_ticket()，而$_COOKIE['guarantee_ticket']仍未定义，并且(cookie(需要定义页面重新加载。

如何使用PHP重新加载该页面？

我知道header("Location: ...")将用于重定向。但是我如何保留该过程并进行重定向？

问题是为什么您需要在请求处理时重新加载页面(在HTTP机制中是不可能的(

所以我有一个想法可以解决此问题(通过将cookie数据传递给子功能(：

public function save_problem(Request $request)
{
    $doesnot_turn_on = isset($request->doesnot_turn_on) ? $request->doesnot_turn_on : "";
    $cookie_data = ["title"=>$request->problem_title, "description"=>$request->problem_description, "turn_on" => $doesnot_turn_on, "unique_product_id" => $request->unique_product_id];
    $res = setcookie('guarantee_ticket', json_encode($cookie_data), time() + 200000, "/");
    if ( Auth::check() ){
        return $this->register_guarantee_ticket();
    } else {
        return redirect()->route('short_register',["des" => route('register_guarantee_ticket')]);
    }
}
public function register_guarantee_ticket($cookie_data)
{
    $problem = $cookie_data; // No need this assign, but I put it here to point out you should pass cookie data directly to sub-function
    .
    .
