Question

i have seen in some libraries something like this :

$this->getResponse()->setRedirect($returnUrl);

How is this ‘multicall’ done, or, how should the class be build to do something like this?

I think :

class greeting
{
    public function hi()
    {
        public function howAreYou()
        {
            echo 'How are you?';
        }
    }
}
$greet = new greeting;
$greet->hi()->howAreYou();

But i think it’s not so good, i would better use something like extends, but i don’t know. Thx for your suggestions.

If this is a class instance calling itself, it is called “method chaining”.

In PHP, can be done by using return $this; note that this is a very different mechanism than class inheritance – it doesn’t really make sense to treat them as interchangeable.
