Question

I’m trying to improve my OOP skill. Recently, I’ve read an article that has this code structure:

$this->getUserInfo()->display();

When I code, I just do something like this:

$this->getUserInfo();

How do I do something like the above…”multiple-passing” or whatever it’s called. I think it’s cool if I can make my code be able to do that…just looking at the code…I’m impressed.

Can somebody post a code something replicating the above…I want to try it too. I want to learn how^^

Thanks!

The trick is to simply return an object from the getUserInfo() method, often the method returns the object it belongs to, i.e. $this.

function getUserInfo() {
    // do something
    return $this;
}
