Question

I was under the impression that the following concept would work, but the new value of $foo isn’t passed between functions. What is the correct way to do this?

class doSomething
{

    public $foo = "good";

    public function changeFooAgain()
    {
        $this->foo = "best";
    }

    public function changeFoo()
    {
        $this->foo = "better";

    }   

    public function getFoo()
    {
        $this->changeFoo();
        $this->changeFooAgain();

        return $this->foo;
    }


}

$foo = new doSomething;

print $foo->getFoo();

I am under the impression that :

• Your code is correct
• And that the foo property is being accessed from each method.

If I execute your code :

• The getFoo() method is executed
• In turn,
  • the changeFoo() method is executed — foo is now better
  • and the changeFooAgain() method is executed — foo is now best
• getFoo() returns the current value of the foo property
• And best (which is the last value that was assigned to the foo property) gets displayed
