1) First way
1）第一种方式
use App\Http\Controllers\OtherController;
class TestController extends Controller
{
public function index()
{
//Calling a method that is from the OtherController
$result = (new OtherController)->method();
}
}
2) Second way
app('App\Http\Controllers\OtherController')->method();
Both way you can get another controller function.

If they are not in the same folder, place use namespace\to\ExampleClass;on top of your file, then you are able to instantiate your controller.
如果它们不在同一个文件夹中，请将其use namespace\to\ExampleClass;放在文件的顶部，然后您就可以实例化您的控制器。

Let's say I have Controller1 and Controller2. I want to call a function of Controller1 from inside a function placed in Controller2.
假设我有 Controller1 和 Controller2。我想从 Controller2 中放置的函数内部调用 Controller1 的函数。
// Controller1.php
class Controller1 {
public static function f1()
{
}
}
And on the other controller:
在另一个控制器上：
// Controller2.php
use App\Http\Controllers\Controller1;
class Controller2 {
public function f2()
{
return Controller1::f1();
}
}
Points to be noted:
需要注意的点：
- f1() is declared static
- f1() 被声明为静态

A call to a controller from inside another controller is a bad idea. There is no sense of meaning of controllers then. You should just redirect to web.php to save safe whole architecture like this:
从另一个控制器内部调用控制器是一个坏主意。那么控制器的意义就没有了。您应该重定向到 web.php 以保存安全的整个架构，如下所示：
class MyController {
public function aSwitchCaseFunction(Request $requestPrm){
...
//getting path string from request here
...
switch($myCase){
case CASE_1:
return redirect()->route('/a/route/path');
....
}
}
}
