Which is better? (add->news or news->add)

[eluser]Vi.[/eluser]
I want to ask for advice about PHP application coding pipeline.
I noticed that "add->news" is better but not sure. There are three main action to control content. (add, delete, update)

Which is better for mid-sized project (e-commerce, dating site, commercial site)?

Code:

$this->Main->add("news");
$this->Main->update("news");

or

Code:

$this->News->add();
$this->News->update();

or

Code:

$this->Add->news();
$this->Update->news();
