如何将变量从子函数传递给父函数（Laravel）

I want to pass the $new_token variable from verified function in app to the verify function in controller. but I dont know how.

My Controller:

public function verify($token)
{
    User::where('email_token',$token)->firstOrFail()->verified();


// I want to bring back variable $new_token from verified function
    $email = new EmailAdmVerification(new User(['email_token' => $new_token, 
    'name' => $user->name]));         
    return redirect('login');
}

My App

public function verified()
{
    $new_token = str_random(10);
    $this->email_token = $new_token;
    $this->save();
}

Thanks you very much for any help or feedback

Just return it from your function:

public function verified()
{
    $new_token = str_random(10);
    $this->email_token = $new_token;
    $this->save();

    return $new_token; // <----
}

Now that this method returns your desired value, you can retrieve it wherever you need it:

 public function verify($token)
{
    $new_token = User::where('email_token',$token)->firstOrFail()->verified(); // <--

    $email = new EmailAdmVerification(new User(['email_token' => $new_token, 
    'name' => $user->name]));    

    return redirect('login');
}
