Это мой код 

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Symfony\Component\HttpFoundation\Response;


class LoginController extends Controller
{
    public function login(Request $request) {
        $response = $request->all();
        print_r($response);
        $email = '';
        $password = '';
        foreach($response as $item) {
          $email = $item['email']
        }
        if($this->checkIfValid($email, $password) == true)  {
          $user = DB::Select('select * from user where email = ?', ['email' => $email]);
          var_dump($user);
        } else {
          return response()->json(['error' => 'Cant validate email and/or password']);
        }
    }

    private function checkIfValid($email, $password)  {
      if($email != '' && $password != '')  {
          echo('test');
          if(filter_var($email, FILTER_VALIDATE_EMAIL) == True) {
            echo('test2');
            return true;
          }
      } else {
        return false;
      }
    }

    private function checkEmailExists($email, $dbemail) {
      if($email == $dbemail)  {
        return true;
      } else {
        return false;
      }
    }
}

, и он дает мне эту ошибку:

Не нужно l oop ответ $. Вы можете просто сделать 

$email = $response['name'];

или непосредственно по запросу экземпляра 

$email = $request->email;

Вместо того, чтобы писать свои собственные логи проверки c, вы можете использовать проверку Laravels. Что-то вроде: 

public function login(Request $request) {

   $request->validate([
        'email'    => 'required|string|email',
        'password' => 'required|string'
   ]);

   ...
}

или просто проверьте, присутствуют ли значения в запросе 

if ($request->has(['email', 'password'])) {
    ...
}

Обновление, чтобы ответить на вопрос автора в комментарии

Допустим, вы dd($response), и вы получите что-то вроде: 

array:3 [▼
  "_token" => "r3hr..."
  "email" => "john.doe@gmail.com"
  "password" => "1234"
]

Когда вы проповедуете это 

foreach($response as $item) {
    // $item here is the value 
    $email = $item['email']; // you can't do this

    $email = $item; // this you could do but it would overwrite each time
}
