Operator question

[reddog]

This might is a newbie/stupid question.  But, what does this operator below means?

Object Operator.

Method chaining is read left to right (left associative):

<?php

 

class Test_Method_Chain

{

    public function One()

    {

        echo "One" . PHP_EOL;

        return $this;

    }

 

    public function Two()

    {

        echo "Two" . PHP_EOL;

        return $this;

    }

 

    public function Three()

    {

        echo "Three" . PHP_EOL;

        return $this;

    }

}

 

$test = new Test_Method_Chain();

 

$test->One()->Two()->Three();

 

/* Ouputs:

One

Two

Three

*/

?>

I did not know you could call multiple functions at once from the same class just by using extra operators.

 

Thanks.
