I would be grateful if someone explained to me the use of double arrow notation in PHP. I suggest is a double classes and instantiation of that classes, but I am not sure. Some examples will be good. Thanks.

Something like this:

$obj->prop->methd();
php oop

As long as your method returns an object you can call the methods of that object too, and so on.

So here's an example of how you can chain methods of a class.

<?php
class MyTest {
    public function Hello() {
        echo "Hello ";
        return $this;
    }

    public function World() {
        echo "World!";
    }
}

$h = new MyTest();
$h->Hello()->World();
?>
