Custom Rule Object

One way to do it is by using Custom Rule Object, this way you can define as many rule as you want without need to make changes in Providers and in controller/service to set new rules.

php artisan make:rule NumericArray

In NumericArray.php

namespace App\Rules;
class NumericArray implements Rule
{
   public function passes($attribute, $value)
   {
     foreach ($value as $v) {
       if (!is_int($v)) {
         return false;
       }
     }
     return true;
   }


  public function message()
  {
     return 'error message...';
  }
}

Then in Form request have

use App\Rules\NumericArray;
.
.
protected $rules = [
      'shipping_country' => ['max:60'],
      'items' => ['array', new NumericArray]
];
