I need to make some regex pattern form url which have 4 patterns:

        $builder
            ->add('url', UrlType::class, array(
                'label' => false,
                'constraints' => array(
                    new NotBlank(array(
                        'message' => "Url nie może być pusty"
                        )),
                    new Regex(array(
                        'pattern' => '/^(http[s]?:\/\/){0,1}(www\.){0,1}[a-zA-Z0-9\.\-]+\.[a-zA-Z]{2,5}[\.]{0,1}/',
                        'match' => true,
                        'message' => 'Podany url jest nieprawidłowy.'
                        )))
