From Laravel 5.5 on you can use an artisan command to create a new Rule which you can code regarding your requirements to decide whether it passes or fail.
Ej: php artisan make:rule PhoneNumber
Then edit app/Rules/PhoneNumber.php, on method passes
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
return preg_match('%^(?:(?:\(?(?:00|\+)([1-4]\d\d|[1-9]\d?)\)?)?[\-\.\ \\\/]?)?((?:\(?\d{1,}\)?[\-\.\ \\\/]?){0,})(?:[\-\.\ \\\/]?(?:#|ext\.?|extension|x)[\-\.\ \\\/]?(\d+))?$%i', $value) && strlen($value) >= 10;
}
use App\Rules\PhoneNumber;
$request->validate([
'name' => ['required', new PhoneNumber],
