Question

Ideally I would like to do something like this….

$formElement->addValidator
(
    (new RegexValidator('/[a-z]/') )->setErrorMessage('Error')
    // setErrorMessage() returns $this
);

Of course PHP won’t allow that, so I settle for this…

$formElement->addValidator
(
    RegexValidator::create('/[a-z]/')->setErrorMessage('Error')
);

And the code in the Base class….

static public function create( $value )
{
  return new static( $value );
}

I would like to go one step further and do something like this…

static public function create()
{
  return call_user_func_array( 'static::__construct', func_get_args() );
}

Again, PHP won’t allow me to do this. I could code individual ‘create’ methods for each validator, but I want it to be a little more slick.

Any suggestions please?

Use ReflectionClass::newInstanceArgs from Reflection API:

$class = new ReflectionClass(__CLASS__);
return $class->newInstanceArgs($args);
