validation in laravel

enum
  'priority'      => ['required', 'in:normal,meduim,high'],	
integer
  'department_id' => 'required|integer',
string
  'email' => 'required|email|unique:users',
  'title'         => ['required', 'min:3'],
  'name' => 'required|max:120',
integer
	'phone' => 'required|regex:/(01)[0-9]{9}/'
  	'phone' => 'required|numeric|phone_number|size:11'
  	'PHONE' => 'required|regex:/(0)[0-9]/|not_regex:/[a-z]/|min:9',


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],
]);
