Question

PHP

What does the second line of code in the index method of the controller (Phalcon) do?

public function indexAction() {
        $this->persistent->parameters = null;
...

Answer 1

read here ! This is an object whose properties are stored within a class. In your case, it's the parameters property, which obviously resets the parameters for the class.

Answer 2

Obviously, it sets $this->persistent->parameters to null.
In general, open the documentation, it will indicate.
If you understand correctly, then see the phalcon documentation on controllers.

Answer 3

The law of Demeter is violated here: https://ru.wikipedia.org/wiki/%D0%97%D0%B0%D0%BA%D...
It is better not to write such code.
