How to use validation on an array element?

Question

Laravel

function($name, $email, $password) {
            ($user = new User)->forceFill([
                'name' => $name,
                'email' => $email,
                'password' => Hash::make($password),
                'email_verified' => '1',
            ])->save();
                $user->setRolesById([1]);
        });

creating a user, you need to hang up validation on email.
